Abstract:We discuss abelian 3d N=2 theories T[,U(1)] engineered by plumbing manifolds . Time permitting, we will discuss a number of related results, such as the cluster structures and Newton-Okounkov bodies determined for the exceptional family in [Spacek-Wang22], and connection to other mirror symmetry statements such as the quantum D-module isomorphism proven for minuscule homogeneous spaces in [Lam-Templier17]. The derivations listed in 0705.3024 seem to fall into three classes: String Theory (D-brane/String state counting, AdS/CFT, Fuzzballs) Infinite Analysis 13 Autumn School on Quantum Dilogarithm, Modular Double, and Representation Theory. Rafa R. Suszek, Louis Alvarez-Gaume [Slides] [Video], Netta Engelhardt (MIT) We therefore relate differential and enumerative geometry, topology and geometric representation theory in mathematics, via a maximally-supersymmetric topological quantum field theory with electric-magnetic duality in physics. More operators/functions can be easily defined with the Calculation.defineOperator method: If you don't want to use eval you will have to use an existing expression evaluator library. Abstract: Knizhnik-Zamolodchikov equation, originally found in the context of a two dimensional conformal field theory, has recently been found in the context of instanton counting, albeit with a significantly extended domain of allowed parameters (level, spins etc). We propose that the matching of 5d coulomb branches plus the 2-group structure constants determined by the higher form symmetry of LSTs as criteria to predict heterotic T-dual candidates.The exploitation are generalized by picking non-trivial flat connections at the infinity to break E8 and Spin(32)/Z2 into their subgroups and confirm these T-dualities by the matching of criteria aforementioned. It seems that no one in the string theory community dares to publicly breathe a word of skepticism. IMPA, Rio de Janeiro, June 14 18, 2021 Turned into an online event. 3. [Slides], Elise LePage (University of California, Berkeley) Hirosi Ooguri (Caltech & IPMU) This topic has been recently explored,from several differentperspectives,by Kontsevich-Soibelman and Doan-Rezchikov. Following Nimas final recommendation, an experimentalist and a string theorist hang out together. Strings 2022 Summary Talk. 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. [Slides] [Video], Fabian Ruehle (Northeastern University) Suomynona, The only message I hear repeatedly is that String theory is the only game in town. With what result? CRM, Montreal, Canada. It has a beautiful combinatorial structure as well as connections to statistical physics, integrable systems, and scattering amplitudes. Paraphrasing Fermat, I have discovered the ugly truth of this, which this margin is too narrow to contain. Nevertheless, it may be worthy registering on this blog some of those problems which arent enough emphasized. Its very good but he often leaves the reader a lot to figure out. In this talk, I will review the probabilistic construction and its equivalence with the bootstrap construction used in the physics literature. Title: On topology change in Poisson-Lie T-duality Ill explain this phenomenon, and propose a new effective algorithm for the calculation of the spectrum which is not based on quantum algebra at all (joint work in progress with A. Soibelman). This goes without saying all technically challenging fundamentally important problems required for superstring theory unification be at least mathematically self-consistent have been left unanswered. rev2023.3.3.43278. Abstract: In this talk I will introduce a refined notion of Gopakumar-Vafa invariants on singular Calabi-Yau threefolds that generate a discrete gauge symmetry in M-theory. Title: The character of M-theory [Slides] [Video], Yaping Yang (University of Melbourne) NN-QFT Correspondence. Since its online only, talks are much more accessible than usual (and since its free, over 2000 people have registered to in principle participate via Zoom). [Slides], Ioannis Lavdas (LMU Munich) Symmetries, Horizons, and Black Hole Entropy [https://arxiv.org/abs/0705.3024] 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). [Slides] [Video], Pierrick Bousseau (ETH Zrich) Estrada Dona Castorina 110, Jardim Botnico In this talk I will introduce the heterotic G2 system and show how to construct families of solutions using homogeneous 3-Sasakian manifolds with squashed metrics. I think I was doing him a favor by not quoting that kind of thing, which he really should be embarrassed about. 2. A better version was given September 22, 2021 at Yan Soibelman's M-seminar. , self-confidence, went through a Faustian-like monologue, if you allow me a little of prose: Ive studied, Schwarz, alas, Polchinski, If people think carrying on this argument is a good use of their time, they are encouraged to do so elsewhere. 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. Juan Maldacena The unitary equivalence relation implies a duality between the modular flow and time evolution. 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. nagrod Salema, nagrod Matematycznego Instytutu Claya, nagrod New Horizons in Mathematics. Find centralized, trusted content and collaborate around the technologies you use most. Rio de Janeiro, RJ, CEP 22460-320, Brasil Everything is in the description. When the quiver comes from a smooth local toric Calabi-Yau 3-fold, we obtain a generalization of shifted Yangian, which acts on the cohomology of the moduli space of certain sheaves of the 3-fold. StringBufferStringBuilder 1. Sorry, but deleted various attempts to carry on the experimentalist vs. theorist mudfight of Ellis_AND_Wooster/Andr. The series of String-Math conferences has developed into a central event on the interface between mathematics and physics related to string theory, quantum field theory and neighboring subjects. Math 302 (Vector Analysis and Integration on Manifolds) Spring 2021. As a result, he sees the current situation as. [Slides]. Does a barbarian benefit from the fast movement ability while wearing medium armor? We study an open quantum many body spin system to check whether its integrable and chaotic regimes can be distinguished by looking at the non-unitary dynamics of a simple operator in Krylov space. I suppose I shouldnt have even let that get started. This uses a combinatorial algorithm computing certain types of GromovWitten invariants encoded in a scattering diagram. [Slides] [Video], Wei Li (Chinese Academy of Sciences) Chrome's Content Security Policy will still throw EvalError, Creating constructor doesn't make sense here and it takes unnecessary resources. This is based on joint work with Raghavendran. for Fundamental Research), [D] Juan Maldacena (Institute for Advanced Study), [T] Shiraz Minwalla (Tata Inst. Edward Witten (Institute for Advanced Study) To address the problem of quantization of a space with gauge fields, first the structure that in the smooth (i.e. We demonstrate the duality of quantum chaos quantities in the thermofield double state defined in a fermionic system. Title: Families of solutions of the heterotic G2 system The LQG derivation, involving an ad-hoc choice for the Immirzi parameter Abstract: I will be discussing my recent work [2110.08179] with Chris Blair and Dan Thompson on topology change in Poisson-Lie T-duality with spectators (i.e. Using Hands-On Tools to Monitor Progress and Assess Students in Math. There is also an open source implementation on GitHub, evaluator.js, and an NPM package. Sen is saying hell give up on string theory if people prove that string theory is inconsistent, but Minwalla and Witten are saying there is no definition of the term string theory. Leszek Hadasz (Jagiellonian University) Talks are available for watching every day via Youtube, links are on the main page. If you cannot make it work with a default operator, I suggest you ask a new question, pointing out where exactly you get stuck. This is joint work with Mark Gross. This relation originally developed from the point of view of matrix models, was later studied from the point of view of conformal field theory. [Slides] [Video], Sunghyuk Park (California Institute of Technology) IMPA, Rio de Janeiro, June 14 - 18, 2021- Turned into an online eventSpeaker: Simon Donaldson (Imperial College)Lecture title: Calibrated geometry and gauge . lun, lectures on Physics at Future Colliders at the ICTP summer school on particle physics, talk on Connecting String Theory to the Real World We See Outside Our Windows, https://sites.google.com/unifi.it/scri21/program, https://www.youtube.com/watch?v=WwmxaXTnGMI, https://www.youtube.com/watch?v=hk_6EtWUatM. These symmetries vastly generalize the standard notion of global symmetries, and can be used in a similar way to obtain insights into strongly-coupled physical phenomena. Piotr Kucharski (University of Amsterdam) [Slides], Pawe Ciosmak (IDEAS NCBiR) Enjoy. The EMS prizes are always a good indication of future Fields medalists Starting from 1h14m of this meet the public vide But this is just an opinion. On the utility of the equation 2+4=6 in supersymmetric quantum field theory. operators, and function (e.g. 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. Abstract: Cosmic censorship as a conjecture about classical General Relativity is now understood to be false in both higher dimensional asymptotically flat space and four-dimensional AdS. Shing-Tung Yau (Harvard University), The interpretation of semiclassical gravity as an average of CFTs has provided much progress in understanding the factorization problem and the information paradox. Title: Heterotic little strings, T-duality and 2-group symmetries Sheldon Katz (University of Illinois) Abstract: Recently there has been lots of activity surrounding generalized notions of symmetry in quantum field theory, including categorical symmetries, higher symmetries, noninvertible symmetries, etc. We have a lunch on the 4th floor of Physics South before the seminar. As Peter keeps on repeating, the denial of the string community to acknowledge the failure of string theory as a unification theory (which is nothing to be ashamed off: physics is full of beautiful theory that are not correct) is a shame for the physics community. More information can be found here Thematic trimester on vertex algebras: Are there any actual attempts in the literature to build such an intrinsically quantum theory, or is this just pie in the sky? Abstract: Superconformal field theories with 8 supercharges in spacetime dimensions 3 to 6 have a large moduli space of vacua. The only game in town in fundamental physics now is to give up on a theory of the real world. Why are trials on "Law & Order" in the New York Supreme Court? In the ending remark, Ooguri makes the observation that the percentage of speakers older than him is roughly a linear function (64-2x)% where x is the number of years after his PhD. Hello, Robert A. Wilson [Slides] [Video], Rajesh Gopakumar (ICTS, Bangalore) Abstract: I will explain how to explicitly calculate knot homology using the Fukaya category associated to a 2d Landau-Ginsburg theory, which is the equivariant mirror of the Coulomb branch of a 3d $mathcal{N}=4$ theory. Thank you. Title: Smoothing, scattering and a conjecture of Fukaya [online talk] AP Computer Science A 2021-22. Abstract: We will discuss how dualities of quantum field theories can be understood as analogous to Morita equivalences for algebras of various types. This is exactly the place where you should be using eval(), or you will have to loop through the string and generate the numbers. Physically, flow treesprovide a mesoscopic representation of BPS states as nested multi-centered bound states of elementary constituents. Summary Talk. Even without LQG, there are many ideas on/in QG which are physically well founded. They are exactly solvable in terms of Whittaker functions. Do I need a thermal expansion tank if I already have a pressure tank? Abstract: During my presentation, I will discuss certain equivalences between conformal field theories with a continuous spectrum: Liouville theory, its supersymmetric extension, and models based on the affine su(2) algebra with irrational level. [Slides], Meng-Chwan Tan (National University of Singapore) A place where magic is studied and practiced? Abstract: I will describe a close analogy between the spectral geometry of hyperbolic manifolds and conformal field theory. We hereby certify that, Alex Buchel, THE UNIVERSITY OF WESTERN ONTARIO, In this tutorial, we'll discuss various approaches to evaluate a math expression using Java. [Slides], Mateo Galdeano (University of Oxford) 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.
