Really amazing work! [Slides] [Video], Heeyeon Kim (Rutgers University) -) and postfix (e.g. Title: Quantum duality and Morita theory for chiral algebras [online talk] Asking for help, clarification, or responding to other answers. In addition, distinct tensor branch data obtained from 6D theories with a single instanton inspire us to classify heterotic strings probing ADE singularities. fiendish mathematics and mind-boggling . The two-step procedure involves first finding points on the Calabi-Yau manifold and then approximating the Ricci-flat metric by approximating solutions to the underlying Monge-Ampere equation. Title: Revisiting Heterotic ALE Instantons: F-theory, 2-groups, and T-duality Im no whit wiser than when I began. Yes, I was ignoring some other things they had to say, for example, Arkani-Hameds The proof in these cases uses the notion of 1-form symmetries (= co-dimension 2 topological defects) to express PGL(N)-skein modules as certain twisted SL(N)-skein-modules, and then to further relate these to well-known formulas for the cohomology of twisted character varietiesof surfaces. Goodbye eval()! 2. Using Hands-On Tools to Monitor Progress and Assess Students in Math. Just viewed the last question and answer session. However, I have provided a pure JS solution (w/o eval). of topological string partition functions. I watched the entire video on the Poincare group and, although the path was the same as Weinberg, there was a lot of new information I thought it was excellent. This construction has several advantages and opens perspectives towards generalization to the case of the $cW$-algebras The problem is not that its too new to be evaluated properly, but that its been a failure. 4. 1 Let n be a natural number, n3. In this talk, I will construct a large class of discrete geometric structures in all dimensions that satisfy these two properties, using the theory of hyperbolic buildings. Abstract: I will discuss methods to numerically approximate Ricci-flat metrics for Calabi-Yau n-folds defined as complete intersections in toric ambient spaces. Maxim Kontsevich (IHS) Abstract: Since 2017, knots and symmetric quivers are known to be intimately related via BPS spectra. UBC, Vancouver, Canada. To address this issue, we use the fusion-matrix bootstrap, which is recently developed in the context of the light-cone bootstrap. [Slides], Elise LePage (University of California, Berkeley) This talk is based on joint work with Si Li. In the limit of large covering, we arrive at an even more fine grained picture and see how the moduli space of string worldsheets arises fromthe dual CFT. Abstract: The theory of Categorical Enumerative Invariants (CEIs) is a non-commutative generalization of the theory of Gromov-Witten invariants. Title: Giant Gravitons in Twisted Holography with the exact opposite agenda.. IMPA, Rio de Janeiro, June 14 - 18, 2021- Turned into an online eventSpeaker: Alba Grassi (CERN)Lecture title: Painlev equations, quantum operators and gaug. I just work on Theoretical Physics topics. String-Math 2015, Hainan Island, China (December 31, 2015 - January 4, 2016; How to Quantize Gravity. You are possibly right its now pointless to debate those issues. Adrian, Solutions to this system describe compactifications of heterotic string theory with N=1 supersymmetry on a 7-dimensional manifold. (With exception of a group of very few dedicated researches, to whom I sincerely keep my deep respects.) Studiowaa na uniwersytecie im. for Fundamental Research), [T] Sebastian Mizera (Institute for Advanced Study), [T] Sameer Murthy (Kings College London), [S] Hirosi Ooguri (Caltech and Kavli IPMU), [D] Joo Penedones (cole Polytech. [Slides] [Video], Sunghyuk Park (California Institute of Technology) Please, no more about the only string theory can compute the Black Hole entropy arguments. We will speak about the history of Keplers conjecture. Braces are not supported, am I right? String Theory remains the most magical structure we have encountered in theoretical physics and the magic seems directly connected to the particle physics of the real world Abstract: Holographic tensor networks are discrete models of AdS/CFT that satisfy complementary recovery of quantum information and the Ryu-Takayanagi formula, which relates the boundary entanglement entropy to the area of extremal surfaces in the bulk. This is based on arXiv:2202.01788, with Matilde Marcolli and Sarthak Parikh. [Slides] [Video], Rajesh Gopakumar (ICTS, Bangalore) @adrianmigueldiego: as a mathematical-physics, I have been earring for 20 years that string theory is the only game in town, I have seen the raise of LQG as an opponent to string, and I witnessed the tentative of string theory to kidnap noncommutative geometry claiming that this was nothing but the geometry of string theory. Of course, a few minutes earlier Witten had explained that no one knows what the theory actually is, which means there is no way to show that it is mathematically inconsistent. Title: Category of QFTs and differential cohomology [Slides]. [Slides] [Video], Antoine Bourget (CEA Saclay) The latter approach allows to realize holomorphically and topologically twisted field theories directly as worldvolume theories in deformed supergravity backgrounds, and we make extensive use of this. [Slides] [Video], Conan Leung (Chinese University of Hong Kong) While such boundary conditions are not compatible with topological twists, deformations that define boundary conditions for the topological theories were recently introduced by Costello and Gaiotto. I wonder how to find the number of ternary strings that have at least one 0, one 1 and one 2. To each 3-manifold equipped with a spin^c structure, is supposed to assign a q-series with integer coefficients that is categorifiable and provides an analytic continuation of the Witten-Reshetikhin-Turaev invariants. I do not know if outreach sessions like the ones we witnessed in this Strings-conference are the best idea. Moving away from such orbifold points requires generalizing the flow tree formula from the Abelian category of quiver representations to the derived category of the same. CRM, Montreal, Canada. Properties of the construction are explained both purely in the context of holomorphic field theory and also by engineering the holomorphic theory on the worldvolume of a D-brane. This includes joint work with David Ben-Zvi, David Jordan, Pavel Safronov, Monica Vazirani, and Haiping Yang. The problem with the string theory hype is not that its new, exciting, cutting-edge speculation, rather than well-established. Witten says something about a (possible) theory that is intrinsically quantum mechanical, which seems to mean a theory that does not start with a continuous field and quantise it, and which (therefore) presumably cannot be described in that way. Our brane engineering approach combines the intersecting brane configurations of HananyWitten with recent work of Costello and Li on twisted supergravity. The String Math series of conferences have become an important event for anyone working at the interface between mathematics and theoretical physics (string theory, quantum field theory and adjacent topics), bringing together an interdisciplinary cohort of pure mathematicians and theoretical physicists. Sorry, but deleted various attempts to carry on the experimentalist vs. theorist mudfight of Ellis_AND_Wooster/Andr. The quotes I gave are accurate, and links are provided so that anyone who wants to can see the full context. We highlight prototype examples of elliptically fibered non-compact Calabi-Yau fewfolds and comment on the fate of these symmetries when these spaces become compact. But keep in mind that using the Function constructor in this way is similar to eval() in that the risks may be comparable. In the end, we also consider a two-qubit system to demonstrate that a different entanglement spectrum does not provide the same constraint to $hat{H}$. Title: The character of M-theory How can I find out which sectors are used by files on NTFS? Chen-Te Ma (Asia Pacific Center for Theoretical Physics) and finally I published a package on npm string-math. Why are trials on "Law & Order" in the New York Supreme Court? Physically, flow treesprovide a mesoscopic representation of BPS states as nested multi-centered bound states of elementary constituents. Youre right that I was cherry-picking, but in the sense of ignoring the huge amount of hype about what great progress was being made, and sticking to writing about certain places where people like Arkani-Hamed or Witten chose to address the real problems (which most of the time are studiously ignored). Even without LQG, there are many ideas on/in QG which are physically well founded. Czy wyraasz na to zgod? Title: Non-Invertible Symmetries and Higher-Categories In the case of rank one instantons this factors through a `Heisenberg type super Lie algebra and the story is analogous to Nakajimas action on the Hilbert scheme. [Slides] [Video], Maxim Kontsevich (IHS) The University of Warsaw The University of Warsaw, founded in 1816, is the largest university in Poland and a leading research centre in the country and in this region of Europe. Philip Candelas Of course even his brightest former student couldnt accept that: The experimental community pretty much politely ignores the string theory community, and has, well, since 1974 or so when the analytic S-matrix failed to predict the charmed quark. Odbya stae podoktorskie na uniwersytecie Humboldta w Berlinie oraz uniwersytecie w Princeton w USA, a nastpnie zostaa profesorem w cole Polytechnique Fdrale de Lausanne (EPFL) w Szwajcarii, gdzie od 2018 roku kieruje Katedr Teorii Liczb. StringStringfinal . As an application, I will use conformal bootstrap techniques to obtain new rigorous bounds on the first positive Laplacian eigenvalue of hyperbolic orbifolds. Im sorry if I cannot comment on other approaches to quantum gravity or non-stringy grand unification programs. AP Computer Science A. I hadn't known about this until your post. Title: Finite symmetry in field theory Ta strona wykorzystuje ciasteczka (cookies) w celu zapewnienia maksymalnej wygody w korzystaniu z naszego serwisu. Besides reviews of major developments in the field and specialized talks on specific topics, an important novelty will be several informal discussions involving two researchers and the conference participants. What does "use strict" do in JavaScript, and what is the reasoning behind it? In this talk, I will present a match between the large-N saddles of the correlation functions of determinants with semiclassical D-brane configurations in the dual theory, using a spectral curve construction. I will present a rigorous version of this formula in the context of quivers with potential, which governs the BPS spectrum in type IIA string theory compactified on certain conical Calabi-Yau threefolds, in the vicinity of orbifold-type points in Kahler moduli space. Title: On topology change in Poisson-Lie T-duality You wrote Hirosi Ooguri (Caltech & IPMU) Piotr Sukowski (chair) Infinite Analysis 13 Autumn School on Quantum Dilogarithm, Modular Double, and Representation Theory. It has a beautiful combinatorial structure as well as connections to statistical physics, integrable systems, and scattering amplitudes. Nigel Hitchin (University of Oxford) Depending on the coupling constant and dimension, they exhibit several distinct scaling behaviors (or if you prefer the high energy jargon, various renormalization group flows). The resulting quiver Yangians, together with their trigonometric and elliptic versions, unify various known results and generalize them to a much larger class. E-mail:eventos@impa.br, Number Theory, Strings, and Quantum Physics, Edward Frenkel (University of California), David Morrison (University of California), Boris Pioline (Sorbonne Universit &CNRS), Nicolai Reshetikhin (University of California), Pedro Vieira (Perimeter Institute for Theoretical Physics), Katrin Wendland (Albert-Ludwigs-Universitt Freiburg), Edward Witten (Institute for Advanced Study), Shing-Tung Yau (Harvard University & The Chinese University of Hong Kong), Dan Freed (University of Texas at Austin), Boris Pioline (Universit Pierre et Marie Curie). Interestingly, most of the structures uncovered have a fractal boundary at infinity, which possesses a rich geometric structure. How to check whether a string contains a substring in JavaScript? This provides an enumerative interpretation of the A-model topological string partition function on non-commutative resolutions of the singular Calabi-Yaus. Little string theories also possess T-duality as well as higher form- and group symmetries. Dr. Kessner. Does a barbarian benefit from the fast movement ability while wearing medium armor? This will be done in the language of QP manifolds/symplectic L-infinity algebroids which is convenient for showing the duality is a canonical transformation in string phase space, and also provides glimpses of a generalisation towards U-duality and higher branes. In a different direction, I will in this talk present a conjectural picture relating holomorphic Floer theory of complex integrable systems to Donaldson-Thomas invariants. Everything is in the description. If one knows how to read between the lines, then at this lecture you finally can hear what, in different words, could well be re-phrased as: the search for M-theory using dualities failed. For a so called well defined mathematical theory, cannot be tweaked etc, the number of unsolved issues with it and the claim not understanding what string theory is is inconsistent. Title: Towards F-theory MSSMs We can exhibit for instance a duality between a trivial bundle with abelian isometries and a non-trivial *bibundle* with a nonabelian Poisson-Lie group action. Elliott Gesteau (California Institute of Technology) This community is indeed becoming like a religious cult, something one of the speakers explicitly denied. Abstract:We discuss abelian 3d N=2 theories T[,U(1)] engineered by plumbing manifolds . Abstract: Recently, higher categorical understandings of quantum field theories have been rapidly developing. Is there a way to calculate a formula stored in a string in JavaScript without using eval()? Progress in D=4, N=2 Field Theory, Strings-Math 2012, Bonn, July 2012 Powerpoint presentation here . Title: Integrability check for open quantum systems in Krylov Space So please stop it with this idea that criticising string theory, as Peter does, is not good nor an honest way to communicating about science. a proponent of string theory but also a well-known populariser of science, . . Green and Witten, recto and verso We present a novel construction of such flux vacua in permutation-symmetric multiparameter compactifications, and develop methods for efficiently computing the zeta functions of the corresponding geometries. Condensed matter physics is a quite different story. (Anyway, String Theory is mainly about Quantum Gravity). Here is an implementation of the Shunting-yard algorithm with additional support for unary prefix (e.g. String Math 2021 - Denis Auroux (Harvard University) 2,124 views Jun 14, 2021 32 Dislike Share Save Instituto de Matemtica Pura e Aplicada 99.2K subscribers nagrod Salema, nagrod Matematycznego Instytutu Claya, nagrod New Horizons in Mathematics. It is healthy. But I went through the hard road, being told just to accept all fundamental questions I raised above as unanswered and move on to the cutting-edge problems whatever and whonever decides what these are. Not the answer you're looking for? There are other views, it is a matter of taste. According to this philosophy, connection to particle physics appear[s] hopeless/parochial/unimportant. The program is based on two main ingredients: The complex geometry of the underlying moduli spaces on the one hand, and cluster algebra structures defined by BPS- or DT-invariants on the other hand. It seems that no one in the string theory community dares to publicly breathe a word of skepticism. Enjoy, This solution also clips whitespaces and checks for duplicating operators, e.g. ' The CY manifolds admitting supersymmetric flux vacua can be associated to elliptic, Hilbert, or Bianchi modular forms, depending on the field the complex structure moduli of the CY take values in. https://sites.google.com/unifi.it/scri21/program This feature could come in handy in projects where we want to evaluate math expressions provided in string format. In the present talk we show that the string theory duals of these systems are classically integrable. This is joint work with Constantin Teleman and Greg Moore. One can add superpotentials, which lead to Seiberg-like dualities between plumbing graphs with triangles. Abstract: I will discuss the theory of Dirac operators perturbed by the Coulomb potential in an arbitrary dimension. Abstract: In 2002, Fukaya proposed a remarkable explanation of mirror symmetry detailing the SYZ conjecture by introducing two correspondences: one between the theory of pseudo-holomorphic curves on a Calabi-Yau manifold X and the multi-valued Morse theory on the base B of an SYZ fibration p : X B, and the other between deformation theory of the mirror X and the same multi-valued Morse theory on B. Juan Maldacena Local nodes will be coordinated worldwide for the joint viewing of talks and discussion sessions, and online satellite meetings during other time periods will be linked on this webpage. Even beginning PhD students will no longer believe that ST is the only framework that reproduces BH entropy.

Talks are available for watching every day via Youtube, links are on the main page. Also I explain what is the dimension for a mathematician and why it is an extremely useful concept for everyone. @DKepler Abstract: Twisted holography relates the 2d chiral algebra subsector of N = 4 SYM to the B-model topological string theory on the deformed conifold SL(2,C). This gives the symmetry algebra action on the categorifiedDT. Estrada Dona Castorina 110, Jardim Botnico So, does anyone know about alternatives to eval()? String Math 2021, held online by IMPA, Rio de Janeiro, Rio de Janeiro, June 14 - 18, 2021. Not all N = (0, 4) boundary conditions admit such deformations. Suomynona, commutative) spacetime case is well-known to yield the Yang-Mills(-Higgs) theory, namely almost-commutative manifolds, has to be replaced by its fuzzy counterpart already the classical level. I saw the discussions you refer to. Title: Quivers for 3-manifolds This is based on joint work with Raghavendran. These boring predictions, if confirmed by DUNE, will show that also in experimental physics no real stuff is happening. In this talk, I will review the probabilistic construction and its equivalence with the bootstrap construction used in the physics literature. Ive personally never understood why showing that (unphysical limits of) your quantum theory gives the expected semi-classical result is anything other than a rather weak consistency check on your theory. Pawe Caputa Strings 2021 will be held online during the two-week period June 21 July 2, 2021 from 9:30 15:00 in So Paulo (8:30 14:00 in NY, 14:30 20:00 in Paris). Finally, I will discuss some applications. Abstract: Liouville field theory was introduced by Polyakov in the eighties in the context of string theory. I dont think I was misrepresenting those at all. , self-confidence, went through a Faustian-like monologue, if you allow me a little of prose: Ive studied, Schwarz, alas, Polchinski, https://arxiv.org/pdf/0809.0305.pdf, Already at p.1 one reads, The Problem: According to textbooks, the passage from classical mechanics to quantum mechanics is made by replacing Poisson brackets with commutators. The corresponding Gopakumar-Vafa invariants provide a discrete refinement of the invariants associated to the smooth deformation. Matthias Gaberdiel Abstract: The six-dimensional superconformal field theory associated to an ADE Lie algebra plays a key role in the AGT correspondence. In response to the obvious question about relation to experiment and testability, people have clearly completely given up on this, with nothing to say (other than a bogus claim that string theory makes some prediction about B-mode polarization), going on about how it took thousands of years for the atomic hypothesis to be vindicated. StringBufferStringBuilder 1. LQG calculations claim to reproduce the semi-classical limit. Due to its interaction, the system density matrix and operators within the system Hilbert space evolve non-unitarily. Evaluator.js is used by a desktop calculator application of the same name. Title: Magnetic quivers for Superconformal Field Theories Dan Freed (University of Texas at Austin) At the time I drop those lines, more than 50 years from dual resonance models?, I havent found any convincingly argument. Title: Knizhnik-Zamolodchikov revisited: (non)supersymmetric gauge theories, defects, and localization This is joint work with Mark Gross. 8. https://8ecm.si/prizes, Ashoke Sen has computed the logarithmic corrections to the Bekenstein-Hawking entropy of various standard black hole solutions in this paper. String-Math 2021 conference (IMPA, Rio de Janeiro), [R = Review lecture] ; [D = Discussion session] ; [T = Research talk] ; [P = Public lecture] ; [S = Starting/Summary talks] ; [G = Gong-show talk]. Abstract: We explore little string theories in six dimensions, constructed via F-theory that are dual to heterotic stringswith NS5 branes probing ADE type singularities. Much as I love this general topic, its getting far from the topic of the posting, so Ill just advise: read my book. Our starting point will be the observation that a rich source of discrete gauge symmetries in M-theory are Calabi-Yau threefolds with singularities that cannot be crepantly resolved. Abstract: Currently, there is a strong interest in the study of non-invertible symmetries of quantum field theories. I agree with Felix. Besides reviews of major developments in the field and specialized talks on specific topics, an important novelty will be several informal discussions involving two researchers and the conference participants. Rio de Janeiro, June 18th, 2021. Georgios Linardopoulos (Wigner Research Centre for Physics) Thats interesting, can you give pointers? [Slides], Alex S.
