A ternary string is a sequence of n symbols that has some of the digits 0, 1, 2. 3 years ago, F_K invariants of knot complements in 3-sphere have been proposed. [Slides] [Video], Mirjam Cvetic (University of Pennsylvania) PDF Si Li - GitHub Pages You, sir, are awesome. (ii) Every-time I receive a grant report asking for resources, penned by a senior string theorist, Im already able to guess the 1st lines: ST is the only mathematically consistent candidate for understanding quantum gravity while providing a framework potentially unifying all know fundamental interactions. https://sites.google.com/unifi.it/scri21/program We then show the explicit duality between a specific form of correlators, the spectral form factor, and the Loschmidt echo with $hat{H}_{mathrm{mod}}$. Title: From BPS crystals to BPS algebras Title: Holographic tensor networks from hyperbolic buildings Boris Pioline (Universit Pierre et Marie Curie) operators, and function (e.g. A Triangle of Influence: Bringing Together Physics, Pure Mathematics, and Computer Science. [Slides] [Video], Dalimil Mazac (IAS) Here's a quick basic example I came up with (updated (2011-06-26): cleaner w/ input boxes). We also discuss generalizations to b_2^+(X)>1. String Math 2021 - Lara Anderson (Virginia Tech) - YouTube IMPA, Rio de Janeiro, June 14 - 18, 2021- Turned into an online eventSpeaker: Lara Anderson (Virginia Tech)Lecture title:. We prove a reformulation of the main conjecture in Fukayas second correspondence, where multi-valued Morse theory on the base B is replaced by tropical geometry on the Legendre dual B. Matilde Marcolli Probably the best answer. @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. [Slides] [Video], Yaping Yang (University of Melbourne) It is expected that the right mathematical structure to capture physical properties of such symmetries is that of higher-categories. There is also an open source implementation on GitHub, evaluator.js, and an NPM package. How do I replace all occurrences of a string in JavaScript? I suppose I shouldnt have even let that get started. One can add superpotentials, which lead to Seiberg-like dualities between plumbing graphs with triangles. String Math 2021 - Simon Donaldson (Imperial College) - YouTube From a mathematical perspective, these solutions involve interesting constructions in geometry such as integrable G2-structures and G2-instantons. Abstract: I will present some conjectures for higher-rank K-theoretic Donaldson-Thomas theory on toric three-folds, and some lessons that we learned from working equivariantly on non-compact spaces. Title: Liouville conformal field theory: from the probabilistic construction to the bootstrap construction Title: Bootstrapping AdS/BCFT If youre so concerned about the public or physics community getting misled, surely youve contacted the organizers of and participants in the conferences Outreach activities , To this I was referring with my phrase 2. It seems that non-stringy approaches to quantum gravity are not very successful at reproducing these universal results. My talk will be based on recent joint work with Baej Ruba. I will discussa phenomenon similar to Frobenius of modular representation theory. Just viewed the last question and answer session. Abstract: Trace map on deformation quantized algebra leads to the algebraic index theorem. [Slides] [Video], Boris Pioline (Sorbonne Universit and CNRS) Abstract: The spectrum of BPS states in D=4 supersymmetric field theories and string vacua famously jumps across codimension-one walls in vector multiplet moduli space. 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. Abstract: Three-dimensional N =4 supersymmetric field theories admit a natural class of chiral half-BPS boundary conditions that preserve N = (0, 4) supersymmetry. Another talk of Penrose (and a conference in his honour): Hope you will find them as a useful starting point. 11. There will also be a gong show session of 5-minute talks by PhD students and a poster session using Zoom breakout rooms. We revisit this construction, working directly in the setting of the holomorphically twisted theory and viewing the topological twists as further deformations. [Slides] [Video], Fabian Ruehle (Northeastern University) Title: The higher dimensional tropical vertex 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]. Rafa R. Suszek, Louis Alvarez-Gaume Abstract: We discuss the partition functions of topologically twisted 5d SU(2) supersymmetric Yang-Mills theory on X x S1, where X is a smooth closed four-manifold. We have a lunch on the 4th floor of Physics South before the seminar. In the discussion section, Vafa challenges him on this, saying he sees no indication that quantum information theory gives any insight into dualities he sees as the central aspect of the non-perturbative theory. The next String Math conference will take place on July 10-14, 2023, at the University of Melbourne in Australia. August 2-7, 2021: International Congress on Mathematical Physics (ICMP) 2021 (session Quantum Field Theory), Geneva, Switzerland. The problem is not that its too new to be evaluated properly, but that its been a failure. All major operations, constants, and methods are supported. with the exact opposite agenda.. Zygmunt Lalak 2013 Jul. 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). 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. String-Math, June 2013. de Lausanne), [D] Nathan Seiberg (Institute for Advanced Study), [T] Ashoke Sen (Harish-Chandra Research Institute), [R]Shu-Heng Shao (Institute for Advanced Study), [T] Yuji Tachikawa (Kavli IPMU and U of Tokyo), [T] Gregory Tarnopolsky (Carnegie MellonU), [T] Gonzalo Torroba (Centro Atmico Bariloche), [D] Edward Witten (Institute for Advanced Study), [G] Ahmadullah Zahed (Bangalore Indian Inst. (With exception of a group of very few dedicated researches, to whom I sincerely keep my deep respects.) But keep in mind that using the Function constructor in this way is similar to eval() in that the risks may be comparable. String theory is now older than not just my students, but also many of their parents and unfortunately its very well-established, sometimes even taught to high school students. Wittens answer is that this was just a vague hope, that the duality ideas are now 25 years old, we havent progressed beyond them, need something new. [Slides], Ioannis Lavdas (LMU Munich) These operators are interesting for several reasons: String Math 2021 IMPA, Rio de Janeiro, June 14 - 18, 2021- Turned into an online event 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. In 2019, S. Gukov and C. Manolescu initiated a program to mathematically construct via Dehn surgery, and as part of that they conjectured that the Melvin-Morton-Rozansky expansion of the colored Jones polynomials can be re-summed into a two-variable series for knot complements. Abstract: By studying M-theory on singular non-compact special holonomy spaces X we demonstrate, via a process of cutting and gluing of singularities that extend to the boundary of X, the appearance of 0-form, 1-form and 2-group symmetries in the resulting supersymmetric quantum field theory. General string perturbation theory using 2d conformal field theory. Title: q-series for so(3) and osp(1|2) String Math 2021, held online by IMPA, Rio de Janeiro, Rio de Janeiro, June 14 - 18, 2021. We construct a trace map on the elliptic chiral homology of the free beta gamma-bc system using the BV quantization framework. Can they make mistakes? Yuya Kusuki (California Institute of Technology) Im no whit wiser than when I began. I just work on Theoretical Physics topics. (UoS & CNRS) Quantum G & of Looijenga pairs Berkeley String-Math 2021 Overview The two main messages: 1ve (different, but equivalent) string-theory motivated enumerative theories built from (X;D) 2they are all closed-form solvable Joint with P. Bousseau (ETH Zrich/Saclay) and M. van Garrel (Warwick/Birmingham). 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. The derivations listed in 0705.3024 seem to fall into three classes: String Theory (D-brane/String state counting, AdS/CFT, Fuzzballs) [Slides] [Video], Maxim Kontsevich (IHS) Possible applications include computing massive string excitations, volumes of non-calibrated cycles, the SYZ conjecture, and approximating solutions to the Hermitian Yang-Mills equations. Poor fool that I am, 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. Piotr Kucharski (University of Amsterdam) Since it's online only, talks are much more accessible than usual (and since it's free, over 2000 people have registered to in principle participate via Zoom). How is Jesus " " (Luke 1:32 NAS28) different from a prophet (, Luke 1:76 NAS28)? Rio de Janeiro, June 18th, 2021. [Slides], Thorsten Schimannek (LPTHE Paris) How to transform string into integers and operators in Javascript? Joerg Teschner (DESY) @David Roberts: There are many references that discuss this from different perspectives. To learn more, see our tips on writing great answers. He notes that to get at non-perturbative string theory we seem to need some more general understanding of quantum theories, going beyond the usual quantization starting with an action, and ends by saying maybe quantum information theory can help. 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. IMPA, Rio de Janeiro, June 14 - 18, 2021- Turned into an online eventSpeaker: Alba Grassi (CERN)Lecture title: Painlev equations, quantum operators and gaug. It seems that no one in the string theory community dares to publicly breathe a word of skepticism. He mentions that one basic problem with this is that there is no understanding of what happens in time-dependent backgrounds, so, in particular, this is useless for addressing the big bang, which is the one place people now point to as a possible connection to real world data. The powerpoint is here in powerpoint and here in pdf . But the time, the community (and the arXiv) takes care of these mistakes. 3. Java-StringStringBuilderStringBufferMath and Physics), [G]Suman Kundu (Tata Inst. The two domain wall systems are thought to be integrable; the evidence comes mainly from the study of correlation functions at weak coupling. I saw the discussions you refer to. [Slides], Peter Spacek (TU Chemnitz) Philip Candelas One reason for this being a real mistake is that, divorced from input from the real world, theory becomes sterile: Questions Posed by Nature are Vastly Deeper and more fruitful than ones we humans tend to pose for ourselves. I will also explain how the Hecke operators from geometric and analytic Langlands correspondence are realized in the four dimensional super-Yang-Mills theory. David Ben-Zwi Title:Plumbing graphs with matter 1+ 2 *2' // 5 but ' 1 + +2* 2 ' // Error, This shows to be more performant than @vol7ron's solution. problemu upakowania sfer w wymiarze 8, a take we wsppracy z innymi matematykami rozwizanie tego problemu w wymiarze 24. [Slides], Nicolo Piazzalunga (Uppsala University) [Slides] [Video], Sam Raskin (University of Texas at Austin) 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. Even without LQG, there are many ideas on/in QG which are physically well founded. How to evaluate a math expression given in string form? Physically, flow treesprovide a mesoscopic representation of BPS states as nested multi-centered bound states of elementary constituents. IMPA, Rio de Janeiro, June 14 - 18, 2021- Turned into an online eventSpeaker: Simon Donaldson (Imperial College)Lecture title: Calibrated geometry and gauge . (Anyway, String Theory is mainly about Quantum Gravity). [Video], Hulya Arguz (IST Austria) We also explain how these invariants and homologies will be categorified in the process, and discuss their higher categorification. TheamplituhedronAn,k,m(Z)is the image of the positive Grassmannian Grk,n0under a positive linear mapRnRk+m. [Slides], Sachin Chauhan (Indian Institute of Technology, Bombay) StringStringBuilderStringBufferMath. Title: Families of Modular Flux Vacua on Symmetric CY Threefolds Off topic, but the European congress of Mathematics has finished up. On the utility of the equation 2+4=6 in supersymmetric quantum field theory. Can I tell police to wait and call a lawyer when served with a search warrant? String Math 2021 - Mina Aganagic (UC Berkeley) - YouTube Adrian Langer Title: Perturbative calculations in twisted 4d gauge theories [online talk] 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. The conference String-Math 2021 which was supposed to be held at IMPA, will be online due to the current pandemic. Abstract: Homological block, commonly denoted by , is a 3-manifold invariant whose existence was predicted by S. Gukov, D. Pei, P. Putrov, and C. Vafa in 2017 using 3d/3d correspondence. Abstract: Liouville field theory was introduced by Polyakov in the eighties in the context of string theory. These boring predictions, if confirmed by DUNE, will show that also in experimental physics no real stuff is happening. 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. 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. of Science), [T] Ying Zhao (Institute for Advanced Study), Luis Alday, Luis Alvarez-Gaume, Kostas Bachas, Micha Berkooz, Nathan Berkovits, Ruth Britto, Horacio Casini, Alejandra Castro, Mirjam Cvetic, Atish Dabholkar, Jan de Boer, Robbert Dijkgraaf, Johana Erdmenger, Mboyo Esole, Jim Gates, Jerome Gauntlett, Rajesh Gopakumar, Mariana Grana, Michael Green, David Gross, Daniel Grumiller, Jeff Harvey, Marc Henneaux, Veronika Hubeny, Marina Huerta, Janet Hung, Antal Jevicki, Clifford Johnson, Shamit Kachru, Igor Klebanov, Zohar Komargodski, Finn Larsen, Yolanda Lozano, Kimyeong Lee, Dieter Luest, Juan Maldacena, Shiraz Minwalla, Jeff Murugan, Rob Myers, Hirosi Ooguri, Leo Pando-Zayas, Silvia Penati, Fernando Quevedo, Eliezer Rabinovici, John Schwarz, Nathan Seiberg, Ashoke Sen, Steve Shenker, Eva Silverstein, Wei Song, Andy Strominger, Tadashi Takayanagi, Sandeep Trivedi, Cumrun Vafa, Pedro Vieira, Anastasia Volovich, Spenta Wadia, Edward Witten, Konstantin Zarembo, A convenient link with all talks at previous Strings meetings is hosted by Yuji Tachikawa at, https://member.ipmu.jp/yuji.tachikawa/stringsmirrors/, All sessions were recorded and are available at the Youtube daily links below or by clicking on the lecture in the, Strings 2021 will be held online during the two-week period.
