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).

SUMMARY:Point-set topology methods in the theory of v-sheaves and diamonds
DESCRIPTION:Seminar on Arithmetic Geometry \nIn this lecture series we aim to introduce the audience to the theory of kimberlites and its applications. 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.

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).

Our main theorem is a comparison of mod $p^r$ Milnor K-groups of $p$-henselian local rings with the Milnor range of a nwly defined syntomic cohomology theory by Bhatt\, Morrow and Scholze. We begin by putting our result into context. Then we sketch the proof which builds on an analysis of a filtration on Milnor K-groups and a new technique called the left Kan extension from smooth algebras.

SUMMARY:Point-set topology methods in the theory of v-sheaves and diamonds
DESCRIPTION:Seminar on Arithmetic Geometry \nIn this lecture series we aim to introduce the audience to the theory of kimberlites and its applications. 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 1: The purpose of this talk is to discuss the point-set topology subtleties that arise from working with non-analytic adic spaces within Scholze’s framework of v-sheaves. We recall miscellaneous aspects of the theory of adic spaces\, perfectoid spaces\, diamonds and v-sheaves. We introduce the small diamond and big diamond functors. We define the “diamond” (or olivine) spectrum of a Huber pair and describe it. We explain explicitly the example of the olivine spectrum of valuation rings. Finally\, we use this topological considerations to “explain” the reversal of closure relations betwenn |Bun_G| and |Isoc_G|. \nIan Glesaon (Berkeley\, USA) \nZoom (Meeting-ID: 635 7328 0984\, Password: smallest six digit prime)

SUMMARY:Depth $0$ local Langlands and cohomology of stacks of global chtoucas
DESCRIPTION:Seminar on Arithmetic Geometry \nLet $G$ be a split reductive group\, $X$ a smooth proper curve over a finite field and $x \in X$ a place. Let $F_x$ the completion of the function field of $X$ at $x$. In this setting\, Lafforgue and Genestier have constructed a semisimple local Langlands correspondence for $G(F_x)$ by geometric methods. In another direction\, DeBacker and Reeder have constructed the depth $0$ part of a local Langlands correspondence by representation theoretic methods. In this talk\, I will discuss some compatibility statement between the two constructions and explain the connection to global chtoucas over $X$. \nArnaud Eteve (ENS\, Paris) \nZoom (Meeting-ID: 635 7328 0984\, Password: smallest six digit prime)

SUMMARY:Locally analytic vectors and rings of periods
DESCRIPTION:Léo Poyeton (Université de Bordeaux) \nBerger and Colmez have shown how to use the theory of locally analytic vectors of  Schneider and Teitelbaum in order to recover classical Sen theory and to generalize it to arbitrary p-adic Lie extensions. After recalling their constructions\, I will explain how some results from Berger can be used to construct rings of periods which “compute” (phi\,Gamma)-modules theories and differential de Rham theory. I will then explain what happens when we try to expand the point of view of Berger and Colmez to higher rings of periods and what results one should expect in this case.

SUMMARY:Arithmetic Quantum Chaos and L-functions
DESCRIPTION:International Seminar on Automorphic Forms \nIn this talk\, I will introduce some aspects of the theory of arithmetic quantum chaos\, focusing on the quantum unique ergodicity theorem for automorphic forms on the modular surface. Then I will give some results on effective decorrelation of Hecke eigenforms and the cubic moment of Hecke-Maass cusp forms. The proofs are based on the analytic theory of L-functions. \nBingrong Huang (Shandong 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:Torsors on valuation rings
DESCRIPTION:Seminar on Arithmetic Geometry \nA 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. \nArnab Kundu (University Paris-Saclay) \nZoom (Meeting-ID: 635 7328 0984\, Password: smallest six digit prime)

SUMMARY:Bloch-Kato groups\, perfectoid fields\, and Iwasawa theory
DESCRIPTION:Gautier Ponsinet (Université Bordeaux) \nThe Bloch-Kato Selmer groups associated with a geometric representation of the Galois group of a number field take part in Bloch and Kato's conjecture on the special values of L functions of motives. In Iwasawa theory\, we are interested in the structure of these Bloch-Kato Selmer groups over infinite algebraic fields extensions. To do so\, we need to study the local Bloch-Kato groups defined via p-adic Hodge theory. In this talk\, I will present new results about the local Bloch-Kato groups over perfectoid fields\, thereby answering a question by Coates and Greenberg in new cases. These local results allow to describe the Bloch-Kato Selmer groups over many infinite extensions as Selmer groups "à la Greenberg" which are easier to handle. If time allows\, I will present immediate consequences of this description in Iwasawa theory.\nlivestream:\nhttp://129.206.106.240/UzPL29kB/mathematikon-seminarraum.html
