Title: Holomorphic boundary conditions for topological field theories via branes in twisted supergravity Title: Integrability check for open quantum systems in Krylov Space This is exactly the place where you should be using eval(), or you will have to loop through the string and generate the numbers. Possible applications include computing massive string excitations, volumes of non-calibrated cycles, the SYZ conjecture, and approximating solutions to the Hermitian Yang-Mills equations.

[Slides]. Unfortunately I dont think Arkani-Hamed has any compelling argument against string theory implies landscape implies nothing to say about particle physics. Organized by Mina Aganagic , Ivan Danilenko , Andrei Okounkov, and Peng Zhou. Berkeley Informal String-Math Seminar. David Morrison (University of California) Yes, I was ignoring some other things they had to say, for example, Arkani-Hameds The corresponding Gopakumar-Vafa invariants provide a discrete refinement of the invariants associated to the smooth deformation. Postal Address:Instituto de Matemtica Pura e Aplicada Physical Review, 85(4), p.631. 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. Share. You, sir, are awesome. In other words, a ternary string is a n-permutation with a repetion of the set {0,1,2}. I just had a look at that session, and more than anything, felt sorry seeing such eminent physicists giving such vacuous reasons just for the sake of defending a theory they have worked on for a long time. [Slides], Aranya Bhattacharya (IISc, Bangalore) String Math 2021 IMPA, Rio de Janeiro, June 14 - 18 Program Break. Adrian Langer 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. I will argue that they are encoded in the topological string partition functions of the singular Calabi-Yau itself and its various non-commutative resolutions. 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. Not the answer you're looking for? This finding suggests that the dual domain wall systems are integrable to all loop orders and for any value of the bond dimension. Jim Halverson In my case, I will give a run, certainly much more healthy, no? Determinant operators in the chiral algebra insert Giant Graviton branes in the dual geometry. We will focus on understanding 3d mirror symmetry viachiralalgebras. Abstract: The D3-D5 and D2-D4 probe-brane systems with nonzero worldvolume flux are holographically dual to N=4 super Yang-Mills and ABJM theory in the presence of half-BPS domain walls. how sensitive is the procedure to choice of k_mu he did the case where k_mu included a boost). Title: Heterotic little strings, T-duality and 2-group symmetries Leszek Hadasz (Jagiellonian University) (With exception of a group of very few dedicated researches, to whom I sincerely keep my deep respects.) 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. Goodbye eval()! 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. This approach is based on 2105.06039 and is joint work with Aganagic and Rapcak. 1. 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 Title: Revisiting Heterotic ALE Instantons: F-theory, 2-groups, and T-duality Title: From BPS crystals to BPS algebras [Slides], Peter Spacek (TU Chemnitz) This community is indeed becoming like a religious cult, something one of the speakers explicitly denied. Nicolai Reshetikhin 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. 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. Equivalent plumbing graphs suggest dual theories. [Slides], Shi Cheng (University of Warsaw) (i) No one convincingly proved the mathematical equivalence between the RNS superstrings and GS formalism. In physical terms, we will discuss a relation between the BPS spectrum of an N=2 4-dimensional field theory and the enumerative geometry of the corresponding Seiberg-Witten integrable system. Adrian, Invertible QFTs are expected to form a sheaf of \infty-groupoids, and we apply the framework of differential cohomology to this sheaf. Strings 2021 started today, program is available here. The spin-bundle required to defined fermion content from SUSY multiplet depends on the metric signature. https://sites.google.com/unifi.it/scri21/program If you cannot make it work with a default operator, I suggest you ask a new question, pointing out where exactly you get stuck. 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. Hawking tells you what the semiclassical limit is. Abstract: The interpretation of semiclassical gravity as an average of CFTs has provided much progress in understanding the factorization problem and the information paradox. Can they make mistakes? StringStringBuilderStringBufferMath. Abstract: One aspect of the relation between physics and arithmetic geometry is the conjectured correspondence between supersymmetric flux vacua and weight-2 modular CY threefolds. The real stuff happens in physics without a press release, book, or blog. 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. Title: BPSDendroscopyon local Calabi-Yau threefolds Participant responses to online questionnaire, Clickhereto use the Slack workspace of Strings 2021. We also provide the action of braiding on the relevant branes, so we can calculate Khovanov homology for any knot given its braid representation. In the end, we also consider a two-qubit system to demonstrate that a different entanglement spectrum does not provide the same constraint to $hat{H}$. It seems that non-stringy approaches to quantum gravity are not very successful at reproducing these universal results. Ironically, the very fact that he had to refer to it at all should alarm them. 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], Meng-Chwan Tan (National University of Singapore) Juan Maldacena 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. I will also discuss a second application, a new definition of FJRW invariants in the presence of an arbitrary symmetry group.

I will then summarise recent work (with Matthias Gaberdiel and others) on the AdS_3/CFT_2 correspondence, in the tensionless limit, which gives a proof of concept of the above ideas. Motived by (twisted) holography (following Costello, Gaiotto, Li, and Paquette) we find a holomorphic model describing the minimal twist of the six-dimensional theory. 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. Math Talks and Number Strings provide the foundation to help students improve their understanding and comprehension of numbers. ), one would at least expect that a well-behaved asymptotically perturbation series follows as one takes into account contributions from all the moduli parameters of Teichmller spaces of Riemann surfaces with higher genus and market points. 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. ncdu: What's going on with this second size column? crickets]. In our examples we find agreement with the flux modularity conjecture of Kachru, Nally, and Yang.

So, does anyone know about alternatives to eval()? Za te oraz inne osignicia otrzymaa wiele prestiowych nagrd i wyrnie, m.in. The whole tone of the discussion was pretty depressing. Discrete mathematics - ternary strings. - Mathematics Stack Exchange 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. Title: Deriving Gauge-String Duality Anyway, truly bold attempt! (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). Finally, we will discuss one recent example (joint with Justin Hilburn) that can be completely understood mathematically: abelian 3d mirror symmetry. String Maths 2021 During the week of June 14-18 we will be hosting a major event in mathematical physics. +1 upvote from me, and I've already used it in a project. Francis (Skip) Fennell | Nov 3, 2021 . Davide Gaiotto While the community just spread out to other problems. All, I just took a look at that session and thought one remarkable point was where people were asked what would cause you to give up on string theory? The only answers forthcoming were from Igor Klebanov, who said he had been working on it his whole life, so couldnt see himself giving up on it, and Ashoke Sen, who said he would only give up on it if it were shown to be mathematically inconsistent. Skeptical challenging of arguments is supposed to be what science is all about, but the speakers in this panel made it seem that this is absolutely not something that is part of their field or what they do. In my talk, I will discuss the following two examples. Title: Automorphic Spectra and the Conformal Bootstrap Sheldon Katz (University of Illinois) Considering two heterotic E8 E8 and Spin(32)/Z2 string theory placed on various background singularities, we expect the heterotic NS5 instantons to fraction.

Berkeley Informal String-Math Seminar I wonder how to find the number of ternary strings that have at least one 0, one 1 and one 2. Exactly because of this. Title: The higher dimensional tropical vertex [Slides] [Video], Netta Engelhardt (MIT) Much as I love this general topic, its getting far from the topic of the posting, so Ill just advise: read my book. 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). 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. Oh, God, how hard Ive slaved away, Of course, these are people. We revisit this construction, working directly in the setting of the holomorphically twisted theory and viewing the topological twists as further deformations. To begin with, we'll discuss a few third-party libraries and their usage. [Slides] [Video], Conan Leung (Chinese University of Hong Kong) Dr. Kessner. Dan Freed (University of Texas at Austin) 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. for Fundamental Research), [D] Juan Maldacena (Institute for Advanced Study), [T] Shiraz Minwalla (Tata Inst. We also explain how these invariants and homologies will be categorified in the process, and discuss their higher categorification. We provide significant evidence that averaging plays an important role in reproducing. Title: Calculating Quantum Knot Homology from Homological Mirror Symmetry Whats remarkable is how powerful Poincare space-time symmetry is as a determinant of how elementary particles behave.

Maxim Kontsevich (IHS) Why are Suriname, Belize, and Guinea-Bissau classified as "Small Island Developing States"? Correlation functions in the worldsheet theory on AdS_3 are shown to agree with those of the dual CFT_2, with both being given in terms of branched covers. These higher-categories are constructed by equivariantizing higher-categories corresponding to invertible higher-form symmetries. But it is clear that these colleagues are attempting to understand topics in QFT and Gravity, with the tools they have at hand. In this talk, I will give a slightly abstract explanation of this phenomenon, at least for the case of a black hole. Zygmunt Lalak The LQG derivation, involving an ad-hoc choice for the Immirzi parameter Braces are not supported, am I right? StringStringfinal . Pyry Kuusela (University of Oxford) Title: Non-rational $widehat{su}(2)$ cosets and Liouville field theory All sessions were recorded and are available at the Youtube daily links below or by clicking on the lecture in the Schedule: Strings 2021 is an annual conference that brings together the entire string theory community. Im posting this since I thought it could be useful for those very busy hep-ph physicists who may wish to go directly to (what I & surely many others) considers as the key moment from perspective lectures. The String Math series of conferences have become an important eventfor 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. String-Math 2015, Hainan Island, China (December 31, 2015 - January 4, 2016; How to Quantize Gravity. Leonardo Rastelli Reimundo Heluani Organizing Committee. Title: Holographic tensor networks from hyperbolic buildings More information can be found here Thematic trimester on vertex algebras: Is a PhD visitor considered as a visiting scholar? This relation originally developed from the point of view of matrix models, was later studied from the point of view of conformal field theory. Little string theories also possess T-duality as well as higher form- and group symmetries. Webinars - hand2mind This construction has several advantages and opens perspectives towards generalization to the case of the $cW$-algebras I will then outline work in progress with Gunningham and Safronov to prove the conjecture in a number of special cases.

[Slides], Kasia Budzik (Perimeter Institute) In other words, the string boundary conditions on the probe branes preserve the integrability of the corresponding Green-Schwarz sigma models. Additionally, Evaluator.js intelligently reports invalid syntax, such as a misused operator, missing operand, or mismatched parentheses. Fall 2021. 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. String Data 2020, CERN, December 2020. In this talk, I will explain how to prove their conjecture for a big class of link complements by making use of the R-matrix for Verma modules. In this talk, I will review the probabilistic construction and its equivalence with the bootstrap construction used in the physics literature. [Slides] [Video], Heeyeon Kim (Rutgers University) In this case, because the string is assumed to be safe and trusted, we would expect use of either eval() or the Function constructor to be reasonable. How would you please implement. [Slides] [Video], Antoine Bourget (CEA Saclay) Im sorry if I cannot comment on other approaches to quantum gravity or non-stringy grand unification programs. [Slides], Sam Gunningham (Montana State University) I suppose I shouldnt have even let that get started. Miranda Cheng It also gives one a feeling for how Arkani-Hamed works through problems. Title: Topological Langlands duality and 1-form symmetries Green and Witten, recto and verso People interested in string theory/LQG religious warfare argue about the calculations in 3. and 4. [Slides], Mateo Galdeano (University of Oxford) Abstract: I will explain some recent and ongoing work on the state spaces associated to 3-manifolds in the Kapustin-Witten twists of 4d N=4 SYM. It would differ in rare case, if this function evil() itself declared some variables which would want to be. I will present recent progress in this direction in the simplest case of local $P^2$, and argue that its global BPS spectrum and flow tree structure can be deduced from a scattering diagram with simple initial data. This topic has been recently explored,from several differentperspectives,by Kontsevich-Soibelman and Doan-Rezchikov. [Slides] [Video], Dan Freed (University of Texas at Austin) Piotr Kucharski (University of Amsterdam) What hes doing is emphasizing ideas that are often not taught in conventional QFT courses (although they should be). The only message I hear repeatedly is that String theory is the only game in town. StringBufferStringBuilder 1. Other than that, I'd use eval in this case. IMPA, Rio de Janeiro, June 14 - 18, 2021- Turned into an online eventSpeaker: Giovanni Felder (ETH Zrich)Lecture title: Superstring measure and the superper.
