The resulting quiver Yangians, together with their trigonometric and elliptic versions, unify various known results and generalize them to a much larger class. Penroses talk is interesting (https://www.youtube.com/watch?v=hk_6EtWUatM), as is the discussion between him and string folks afterwards. Algorithm methods are divided for each level of operations order as follows: parseFactor = 1. operator sign | variable evaluation | function call | parenthesis (sub-expressions); 2. exponentiation; parseTerms = 3. multiplication, division; parseExpression = 4. addition, subtraction. I do not know if outreach sessions like the ones we witnessed in this Strings-conference are the best idea. 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. I will show how this calculation works for su(2) and give an example. Mhh, you could use the Function() constructor: There's nothing wrong with eval, especially for cases like this. The problem is not that its too new to be evaluated properly, but that its been a failure. I could go on the whole night, but I believe, as most other string theorists do, there are more urgent or at least doable problems to solve now. 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. Oh, God, how hard Ive slaved away, To learn more, see our tips on writing great answers. We revisit this construction, working directly in the setting of the holomorphically twisted theory and viewing the topological twists as further deformations. 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). We investigate a two-dimensional chiral analogue of the algebraic index theorem via the theory of chiral algebras developed by Beilinson and Drinfeld. Title: Giant Gravitons in Twisted Holography Abstract: Holomorphic Floer theory is the analogof Floer theoryfor holomorphic symplectic manifolds. 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. Title: Quantum duality and Morita theory for chiral algebras [online talk] Title: Elliptic trace map on chiral algebras It will often be a good idea to analyze states in terms of these irreducible representations. (i) No one convincingly proved the mathematical equivalence between the RNS superstrings and GS formalism. Title: Holomorphic Floer theory and Donaldson-Thomas invariants Lakshya Bhardwaj (University of Oxford) 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]. What is the !! String theory calculations that can be done in unphysical situations (wrong dimension, lots of SUSY, extremal black holes) claim to reproduce the semiclassical limit. Jim Halverson 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. Title: Calculating Quantum Knot Homology from Homological Mirror Symmetry Georgios Linardopoulos (Wigner Research Centre for Physics) 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. Ivan Ip's Homepage - Hong Kong University of Science and Technology An exchange that was otherwise quite lively and interesting, you paint in the worst possible way. F-theory vacua with exactly one Higgs field and no vector-like exotics. Katrin Wendland, Ron Donagi (University of Pennsylvania) Following Nimas final recommendation, an experimentalist and a string theorist hang out together. But regarding superstrings, from such a strong statement one would expect at least proof (not rigorously by mathematical standards of course!) Title: Perturbative calculations in twisted 4d gauge theories [online talk] Rafa R. Suszek, Louis Alvarez-Gaume That looks nothing like the real world, and as Minwalla points out, no one at the Strings conference is even talking about that sort of string theory anymore. Abstract: The main goal of this talk is to present a novel conjectural incarnation of Langlands duality in the purely topological setting of character varieties of 3-manifolds and their quantizations via skein theory. 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. 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: I will discuss the theory of Dirac operators perturbed by the Coulomb potential in an arbitrary dimension. IMPA, Rio de Janeiro, June 14 18, 2021 Turned into an online event. How do I check if an array includes a value in JavaScript? 8. Based on joint work with Petr Kravchuk and Sridip Pal. Solutions to this system describe compactifications of heterotic string theory with N=1 supersymmetry on a 7-dimensional manifold. Likely Witten was thinking of things like the 6d (2,0) superconformal theory which has not classical limit and its construction is somewhat mysterious. Enjoy, This solution also clips whitespaces and checks for duplicating operators, e.g. ' I am not a fan of string theory. Sheldon Katz (University of Illinois) These higher-categories are constructed by equivariantizing higher-categories corresponding to invertible higher-form symmetries. Our brane engineering approach combines the intersecting brane configurations of HananyWitten with recent work of Costello and Li on twisted supergravity. I will discussa phenomenon similar to Frobenius of modular representation theory. Jednym z najwaniejszych osigni Maryny Viazovskiej jest rozwizanie tzw. 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).

We hereby certify that, Alex Buchel, THE UNIVERSITY OF WESTERN ONTARIO, Update: At String 2021, yesterday Nima Arkani-Hamed gave a talk on Connecting String Theory to the Real World We See Outside Our Windows, where he sometimes sounds like me, contrasting the pre-LHC claims of string theorists: 1. Their scaling dimensions are related to the Laplacian eigenvalues on the manifold. String Math 2021 - Alba Grassi (CERN) - YouTube So, does anyone know about alternatives to eval()? Reimundo Heluani's Homepage - IMPA This public lecture is also a lecture in the Zapytaj fizyka series here is the lecture website. Estrada Dona Castorina 110, Jardim Botnico Strings 2021 Summary Talk, So Paulo (June 21 - July 2, 2021) [on-line] . We construct a trace map on the elliptic chiral homology of the free beta gamma-bc system using the BV quantization framework. W 2018 zostaa zaproszona jako wykadowczyni podczas Midzynarodowego Kongresu Matematycznego jest to jedno z najwaniejszych wyrnie dla matematykw. Strings 2021 is an annual conference that brings together the entire string theory community. How do I replace all occurrences of a string in JavaScript? Can I tell police to wait and call a lawyer when served with a search warrant? These have been going on for over 25 years, with nothing new in a very long time. The talk is based on work in collaboration with Davide Gaiotto. Adrian Langer They are exactly solvable in terms of Whittaker functions. Exactly because of this. [Video], Hulya Arguz (IST Austria) 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. Hiraku Nakajima The EMS prizes are always a good indication of future Fields medalists (not not) operator in JavaScript? This finding suggests that the dual domain wall systems are integrable to all loop orders and for any value of the bond dimension. Certificates YouTube live YouTube playlist of the lectures TheAttractor Flow Tree conjecture postulates that the BPS index $\Omega(\gamma,z)$ for given charge $\gamma$and moduli $z$ can be reconstructed from the`attractor indices $\Omega_*(\gamma_i)$ counting BPS states of charge $\gamma_i$ in their respective attractor chamber, by summing over all possible decompositions $\gamma=\sum_i \gamma_i$ and over decorated rooted flow trees. The general picture is nicely illustrated by the Borel All, Robert A. Wilson, Thanks for allowing my last comment. Of course, I do not justify equally wrong comments from certain string theorists All, 2013 Nov. Osaka City University, Japan. Matilde Marcolli But keep in mind that using the Function constructor in this way is similar to eval() in that the risks may be comparable. Dan Freed (University of Texas at Austin) In the present talk we show that the string theory duals of these systems are classically integrable. how sensitive is the procedure to choice of k_mu he did the case where k_mu included a boost). Title: Categorical Enumerative Invariants Calculate string value in javascript, not using eval ncdu: What's going on with this second size column? with the exact opposite agenda. The LQG derivation, involving an ad-hoc choice for the Immirzi parameter From the README: Dr. Kessner. To address this issue, we use the fusion-matrix bootstrap, which is recently developed in the context of the light-cone bootstrap. Title: Integrability check for open quantum systems in Krylov Space [Slides] [Video], Antoine Bourget (CEA Saclay) Go on and you certainly will be assured thats not going to be about qubits, Dear Robert. How can I guarantee that my enums definition doesn't change in JavaScript? Cookies and PrivacyAboutEventsNews [Slides], Meng-Chwan Tan (National University of Singapore) String-Math, June 2013. We physically derive (i) a novel Vafa-Witten four-manifold invariant associated with this moduli space, (ii) their relation to Gromov-Witten invariants, (iii) a novel Vafa-Witten Floer homology assigned to three-manifold boundaries, (iv) a novel Vafa-Witten Atiyah-Floer correspondence, (v) a proof and generalization of a conjecture by Abouzaid-Manolescu about the hypercohomology of a perverse sheaf of vanishing cycles, (vi) a Langlands duality of these invariants, Floer homologies and hypercohomology, and (vii) a quantum geometric Langlands correspondence with purely imaginary parameter that specializes to the classical correspondence in the zero-coupling limit, where Higgs bundles feature in (ii), (iv), (vi) and (vii). http://jsfiddle.net/vol7ron/6cdfA/. We are going to perform a construction of such quantum curves using the mathematical language of vertex operator algebras. The qubit example is a bit unfair since in some sense its the quantization of the sphere, although this sphere is not a classical limit of the quantum theory (and sphere isnt a cotangent bundle of some configuration space). Jackiw-Teitelboim/PeterH, Workshop on Algebraic Geometry and Machine Learning, Tsinghua Sanya International Mathematics Forum, January 2021. String theorist: indeed, whats QCD?. Title: Emergence of Time from Unitary Equivalence Title: Automorphic Spectra and the Conformal Bootstrap 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). Hawking tells you what the semiclassical limit is. As a result, he sees the current situation as. June 14-18, 2021: String-Math 2021 (Plenary talk), IMPA, Rio de Janeiro, Brazil. Nikita Nekrasov 3. We focus on $\hat Z$ for $SO(3)$ group and orthosymplectic supergroup $OSP(1|2)$. 2. 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. From a mathematical perspective, these solutions involve interesting constructions in geometry such as integrable G2-structures and G2-instantons. Title: Vafa-Witten Theory: Invariants, Floer Homologies, Higgs Bundles, a Geometric Langlands Correspondence, and Categorification [online talk] 11. Poor fool that I am, Abstract: Open quantum systems are of experimental interest since ideally real life experiments always have some interaction with its environment. On the utility of the equation 2+4=6 in supersymmetric quantum field theory. 10. Robert A. Wilson, The problem with the string theory hype is not that its new, exciting, cutting-edge speculation, rather than well-established. Jacek Paweczyk String Math 2021 - Giovanni Felder (ETH Zrich) - YouTube 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. (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). We have a lunch on the 4th floor of Physics South before the seminar. Title: A Yang-Mills matrix theory Strings 2021 started today, program is available here. Title: Homological blocks and R-matrices problemu upakowania sfer w wymiarze 8, a take we wsppracy z innymi matematykami rozwizanie tego problemu w wymiarze 24. [Slides], Alex S. Arvanitakis (Vrije Universiteit Brussel) Abstract: Three-dimensional N =4 supersymmetric field theories admit a natural class of chiral half-BPS boundary conditions that preserve N = (0, 4) supersymmetry. [Slides] [Video], Edward Witten (IAS) Asking for help, clarification, or responding to other answers. This is based on joint work with Raghavendran. Not the answer you're looking for? 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). [Slides], Ioannis Lavdas (LMU Munich) Abstract: The six-dimensional superconformal field theory associated to an ADE Lie algebra plays a key role in the AGT correspondence. 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). CEIs should be thought of as a precise realization of the general idea, due to Kontsevich, that the category of open strings (plus data of the splitting) determine closed string invariants. Sat 3 Apr 2021 12.00 EDT Last modified on Tue 6 Apr 2021 09.54 EDT. Much as I love this general topic, its getting far from the topic of the posting, so Ill just advise: read my book.
