SUMMARY:The standard conjecture of Hodge type for abelian fourfolds
DESCRIPTION:Guiseppe Ancona (Strasbourg) \nLet S be a surface\, V be the Q-vector space of divisors on S modulo numerical equivalence and d be the dimension of V . The intersection product defines a non degenerate quadratic form on V . The Hodge index theorem says that it is of signature (1\, d − 1). In the Sixties Grothendieck conjectured a generalization of this statement to cycles of any codimension on a variety of any dimension. In characteristic zero this conjecture is a consequence of Hodge theory but in positive characteristic almost nothing is known. Instead of studying these quadratic forms at the archimedean place we will study them at p-adic places. It turns out that this question is more tractable\, thanks to p-adic Hodge Theory. Moreover\, using classical product formulas on quadratic forms\, the p-adic result will give non-trivial informations on the archimedean place. For instance\, we will prove the original conjecture for abelian fourfolds.

SUMMARY:Expanded degenerations for Hilbert schemes of points.
DESCRIPTION:Oberseminar Algebra und Geometrie \nCalla Tschanz (University of Bath) \nAbstract:\nLet X –> C be a projective family of surfaces over a curve with smooth generic fibre and simple normal crossing singularity in the special fibre X_0. We construct a good compactification of the moduli space of relative length n zero-dimensional subschemes on X\X_0 over C\{0}. In order to produce this compactification we study expansions of the special fibre X_0 together with a GIT stability condition\, generalising the work of Gulbrandsen-Halle-Hulek who use GIT to offer an alternative approach to the work of Li-Wu for Hilbert schemes of points on simple degenerations. We construct stacks which we prove to be equivalent to the  underlying stack of some choices of logarithmic Hilbert schemes produced by Maulik-Ranganathan.

DESCRIPTION:Alireza Shavali (Heidelberg University): Link to Galois deformation theory \nExplain some background on Galois deformation theory (cf. [Gee22\, §2\,§3]\, [B¨oc13\, §1\, §3.2]) focusing on introducing the universal framed deformation ring Rρ□ of a local Galois representation ρ : GF → GLn(Fℓ). For G = GLn\, show that the completion of the local ring of the moduli space of L-parameters at an Fℓ-point x ρ recovers Rρ□ (cf.

SUMMARY:Sup-norms of automorphic forms on average
DESCRIPTION:International Seminar on Automorphic Forms \nBounding the sup-norms of automorphic forms has been a very active area in research in recent times.\nWhereas lot of nice results are known for small rank groups\, like GL(2)\, almost nothing is known for\, say\, Siegel or Jacobi modular forms of higher degrees. In this talk we aim to discuss some conjectures and results in this area. We use either the theory of Poincare series or averages of central values of L-functions to tackle this problem. Our methods have the benefit of having a hands-on approach and fits into many situations.\nSoumya Das (Indian Institute of Science) \nYou can join the Zoom meeting at https://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits).

SUMMARY:The Picard-Lefschetz formula for normal crossings
DESCRIPTION:Moritz Kerz (Universität Regensburg) \nAbstract: In the study of semi-stable degeneration of Lefschetz pencils one is led to a generalization of the classical Picard-Lefschetz formula for certain perverse sheaves on normal crossing spaces. In the talk I will recall the formalism of nearby cycle and vanishing cycle functors and I will explain how Hodge theory allows one to obtain the normal crossing Picard-Lefschetz formula. Joint work with A. Beilinson and H. Esnault.

SUMMARY:Gauged Gromov-Witten theory and affine grassmannians
DESCRIPTION:Oberseminar Algebra und Geometrie \nRescheduled to 10.01.2023\, 4pm\, room 308  \nAndres Fernandez Herrero (Columbia University) \nAbstract: Objects of interest in algebraic geometry (e.g. curves\, vector bundles\, or differential equations) are often parametrized by algebraic varieties\, called moduli spaces. In this talk I will discuss some recent techniques developed to construct moduli spaces for a broad range of moduli problems which are related to the moduli of vector bundles on a fixed compact Riemann surface.\nWith time permitting\, I will also try to explain what it means to count vector bundles on compact Riemann surfaces\, and why such counts are given by combinations of certain special values of transcendental functions. This talk is based on joint work with Daniel Halpern-Leistner. \n

SUMMARY:Deligne-Mostow theory and beyond
DESCRIPTION:International Seminar on Automorphic Forms \nBall quotients have been studied extensively in algebraic geometry from the aspect of moduli spaces\, and in number theory with emphasis on the relation with modular forms. The Deligne-Mostow theory gives them moduli interpretation through the isomorphism between the Baily-Borel compactifications of them and certain GIT quotients.\nIn this talk\, I will discuss whether the isomorphisms given by the Deligne-Mostow theory are lifted to other compactifications from the viewpoint of modular forms and pursue “better” compactifications. Moreover\, I will also clarify their connection with the recent development in the minimal model program. This work is based on a joint work with Klaus Hulek (Leibniz University Hannover). \nYota Maeda (Kyoto University) \nYou can join the Zoom meeting at https://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits).

SUMMARY:Homotopical characterization of exceptional complete intersection maps
DESCRIPTION:Janine Letz \nA surjective map between commutative noetherian local rings (R\, m) → S is exceptional complete intersection (eci) if its kernel is generated by a regular sequence that is part of a minimal generating set of m. I present two characterizations of eci maps: First\, a map is eci if and only if the truncated Atiyah class vanishes at the residue field. This establishes a second characterization in terms of the lattices of thick subcategories of complexes of finite length homology. This is joint work with Srikanth Iyengar\, Jian Liu and Josh Pollitz.

SUMMARY:Ruth Moufang Lectures 2022 (1st lecture)
DESCRIPTION:The Ruth Moufang Lectures will have their second iteration on December 21st\, 2022 in Darmstadt. We are happy to announce that our speaker will be Sarah Zerbes (ETH Zürich). The lectures will circle around the BSD conjecture and Euler systems. \n\n1st lecture: Euler systems and the Birch—Swinnerton-Dyer conjecture\n\nAbstract: \nL-functions are one of the central objects of study in number theory. There are many beautiful theorems and many more open conjectures linking their values to arithmetic problems. The most famous example is the conjecture of Birch and Swinnerton-Dyer\, which is one of the Clay Millenium Prize Problems. I will discuss this conjecture and some related open problems\, and I will describe some recent progress on these conjectures\, using tools called `Euler systems’. \nSchedule:\nThere will be tea at 16:45 in S2|15 244.\nThe lecture starts at 17:15 in Uhrturmhörsaal der Physik\, S2 08|171. \nYou can follow the talk online on zoom following the link below. \nJoin Zoom Meeting\nhttps://tu-darmstadt.zoom.us/j/62512397856?pwd=RE9Ea2VpZG5uWWJvd2tuT2hzbzZpUT09 \nMeeting ID: 625 1239 7856\nPasscode: Moufang \nThe second two talks will probably take place in summer 2023.\nLectures 2 and 3 are aimed at mathematicians with a background in number theory while lecture 1 should be accessible for a more general audience.

SUMMARY:Distributions of Manin's iterated integrals
DESCRIPTION:International Seminar on Automorphic Forms\n \nWe recall the definition of Manin’s iterated integrals of a given length. We then explain how these generalise modular symbols and certain aspects of the theory of multiple zeta-values. In length one and two we determine the limiting distribution of these iterated integrals. Maybe surprisingly\, even if we can compute all moments also in higher length we cannot in general determine a distribution for length three or higher. This is joint work with Y. Petridis and with N. Matthes. \nMorten Risager (University of Copenhagen) \nYou can join the Zoom meeting at https://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits).

The theory of kimberlites attempts to single out within Scholze’s category of v-sheaves those objects that “behave” as formal schemes. In this way\, kimberlites provide well-behaved candidates for integral models of locally spatial diamonds. In the first two talks we discuss the foundations of the theory\, and in the second two talks we discuss its applications to study moduli spaces of B_dR-lattices and moduli spaces of p-adic shtukas. \nTalk 4: The purpose of this talk is to discuss the moduli of p-adic shtukas. We prove these moduli spaces are smelted kimberlites and single out the difficulties to proving that they are kimberlites. We discuss the v-sheaf theoretic “local diagram correspondence” for tubular neighborhoods relating moduli spaces of shtukas to moduli of B^+_dR-lattices. We prove they are unibranch. Finally we expalin how this is used to compute their connected components. \nIan Gleason (Berkeley\, USA) \nZoom (Meeting-ID: 635 7328 0984\, Password: smallest six digit prime)

SUMMARY:A motivic integral p-adic cohomology
DESCRIPTION:Alberto Merici (Oslo) \nAbstract: We use the theory of logarithmic motives to construct an integral p-adic  cohomology theory for smooth varieties over a field k of characteristic p\, that factors through the category of Voevodsky (effective) motives. If k satisfies resolutions of singularities\, we will show that it is indeed a “good” integral p-adic cohomology and it agrees to a similar one constructed by Ertl\, Shiho and Sprang: we will then deduce many interesting motivic properties.\nIf time permits\, we will explain how the above construction suggests a strategy to prove a conjecture of Hübner and Schmidt on tame motivic cohomology.

SUMMARY:Residual intersections and Witt-valued Euler numbers
DESCRIPTION:Tom Bachmann \nReport on joint work with Kirsten Wickelgren. Let K = J:I be a (local) residual intersection satisfying appropriate hypotheses. We show that the conormal module J/JK is free and use this to exhibit a *canonical* isomorphism between I^{t+1}/JI^t twisted by the determinant of J/KJ and the canonical module (the derived dual of R/K). Using this we determine the canonical modules of global residual intersections. As an application we show how to interpret the van Straten–Warmt form of an almost complete intersection as arising via algebraic surgery from the Koszul complex. This yields a new local formula in quadratic enumerative geometry.

We prove they are kimberlites in general and we sketch the proof of the representability by formal schemes of the “local models” attached to minuscule cocharacters. We introduce the notion of unibranch kimberlites and explain its relation to normality. We prove that these moduli spaces are unibranch. \nIan Gleason (Berkeley\, USA) \nZoom (Meeting-ID: 635 7328 0984\, Password: smallest six digit prime)

SUMMARY:Torsors on Valuation Rings
DESCRIPTION:Arnab Kundu (Université Paris-Saclay) \nAbstract: A conjecture of Grothendieck and Serre states that a torsor under a reductive group over a Noetherian regular scheme X is Zariski locally trivial if it is generically trivial. Recently\, this conjecture has seen progress through the work of Fedorov\, Panin and Česnavičius. We shall see the historical background of this conjecture\, followed by the techniques that go into the proof of the quasi-split case in the analogous situation when X is a smooth scheme over a valuation ring of rank one.

SUMMARY:Bias in cubic Gauss sums: Patterson's conjecture
DESCRIPTION:International Seminar on Automorphic Forms\n \nWe prove\, in this joint work with Maksym Radziwill\, a 1978 conjecture of S. Patterson (conditional on the Generalised Riemann hypothesis) concerning the bias of cubic Gauss sums. This explains a well-known numerical bias in the distribution of cubic Gauss sums first observed by Kummer in 1846. One important byproduct of our proof is that we show Heath-Brown’s cubic large sieve is sharp under GRH. This disproves the popular belief that the cubic large sieve can be improved. An important ingredient in our proof is a dispersion estimate for cubic Gauss sums. It can be interpreted as a cubic large sieve with correction by a non-trivial asymptotic main term. \nAlexander Dunn (Caltech) \nYou can join the Zoom meeting at https://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits).

We discuss finiteness condtions and the specialization triples principle. \nIan Gleason (Berkeley\, USA) \nZoom (Meeting-ID: 635 7328 0984\, Password: smallest six digit prime)
