SUMMARY:Syntomic descent spectral sequence for arithmetic p-adic varieties
DESCRIPTION:Yicheng Zhou (Paris-Saclay) \nFor a “large” class of rigid-analytic varieties over a p-adic local field\, we explain how to construct a natural syntomic descent spectral sequence compatible with the Hochschild-Serre spectral sequence. As a consequence\, for proper rigid-analytic varieties\, the étale regulators maps on suitable K-theoretic groups factor through their syntomic counterparts\, for suitably defined syntomic Chern class maps.

SUMMARY:International Seminar on Automorphic Forms
DESCRIPTION:Martin Raum (Goteborg): The geometric unitary Kudla Conjecture \nKudla and Millson proved that the generating series of cohomology classes associated with special cycles on orthogonal and unitary Shimura varieties is modular. This yields Siegel modular forms and Hermitian modular forms. In later work\, Kudla conjectured that the analogous generating series of cycles in the Chow group is modular\, too. The orthogonal case of the conjecture was established more than 10 years ago. We resolve the conjecture in the unitary case. In this talk\, we explain in particular the role of automatic convergence results in the theory: how they arise and what techniques we currently have to prove them. \nZoom (680 4828 0736\, The password is the first Fourier coefficient of the modular j-function (as digits)).

SUMMARY:Oberseminar Algebra und Geometrie
DESCRIPTION:Michael Temkin (MPI Bonn): Wild Hurwitz spaces and level structures \n\nAbstract: Hurwitz moduli spaces of covers of curves of degree d are classical and well studied objects if one assumes that d! is invertible and hence no wild ramification phenomena occur. There were very few attempts to study the wild case. In the most important one Abramovich and Oort started with the classical space H_{2\,1\,0\,4} of double covers of P^1 ramified at four points and (following an idea of Kontsevich and Pandariphande) described its schematic closure H in the space of stable maps over Z. The result over F_2 was both strange and informative\, but lacked a modular interpretation. \nIn the first part of my talk I will describe the example of Abramovich-Oort and then tell about a work in progress of Hippold\, where a (logarithmic) modular version of compactified Hurwitz space of degree p is constructed when only (p-1)! is invertible. In particular\, this conceptually explains phenomena observed by Abramovich-Oort. In the second part I will describe another outcome of the same ideas. It was observed by Abramovich-Oort that H is the blowing up of the modular curve X(2). This is not a coincidence\, and the same ideas can be used to refine the wild level structures of Drinfeld and construct modular interpretation of the minimal modifications of the curves X(p^n) which separate ordinary branches at any supersingular point. This is a very recent work in progress and the precise description of the obtained spaces is still to be found.

SUMMARY:International Seminar on Automorphic Forms
DESCRIPTION:Quasimodular forms for the orthogonal group and Gromov-Witten theory\nGeorg Oberdieck (Heidelberg) \nIn this talk we begin by introducing quasimodular forms for orthogonal groups as constant terms of almost-holomorphic modular forms. For this we introduce orthogonal lowering and raising operators. Basic results are the description of the spaces of quasimodular forms in terms of vectorvalued modular forms and the interaction with the theta lift. In particular\, we give a criterion when the theta lift of a quasimodular form is again quasimodular (it is not always the case). In the second part of the talk I will explain how these quasimodular forms appear in the Gromov-Witten theory of Enriques surfaces. They also want to appear in the Gromov-Witten theory of K3 surfaces\, but actually more general automorphic objects there. Based on joint work with Brandon Williams. \nZoom (680 4828 0736\, The password is the first Fourier coefficient of the modular j-function (as digits)).

SUMMARY:Construction of logarithmic cohomology theories
DESCRIPTION:Doosung Park (Wuppertal) \nIn this talk\, I will explain a functor extending cohomology theories from schemes to log schemes. Using this functor\, we can obtain the log cyclotomic trace\, and we can represent K-theory in the logarithmic motivic homotopy category. I will also explain an application to the p-adic deformation problem for the K-theory of semistable schemes.

SUMMARY:Toward the noncommutative minimal model program
DESCRIPTION:The aim of the talk is to introduce the noncommutative minimal model program (ncMMP) proposed by Halpern-Leistner and inspired by some works of Dubrovin and Kontsevich. For a given projective variety X\, the classical minimal model program asks if there is a variety Y that is birational to X but has simpler geometry\, such Y is called a minimal model of X. In the noncommutative context\, we consider the derived category D(X) of coherent sheaves on X\, and we ask if we can decompose it canonically. The biggest factor of the decomposition is then a minimal model for D(X). In order to find such a decomposition Halpern-Leistner proposes to use the quantum cohomology of X.\nWe will discuss some examples where Halpern-Leistner’s proposal is satisfied: Grassmannians\, quadrics\, and cubics in dimensions 3 and 4.

SUMMARY:Seminar on Arithmetic Geometry
DESCRIPTION:Lucien Hennecart (CNRS): The BPS sheaf for preprojective algebras and moduli of Higgs bundles \nIn the first part of the talk\, I will introduce the BPS sheaf associated with the preprojective algebra of a quiver. This is a perverse sheaf on the moduli space of representations\, endowed with a Lie algebra structure\, which encodes the Kac polynomials of the quiver. Its structure is described in terms of generators and relations in joint work with Davison and Schlegel Mejia. This description is formulated in terms of a generalized Kac–Moody algebra. \nIn the second part\, I will explain how this description makes it possible to determine the supports and local systems of the direct summands of the BPS sheaf. This description involves the geometry of hypertoric varieties in general\, and can in certain cases be simplified. Applying these results to the Hitchin fibration\, one recovers results due to de Cataldo\, Heinloth\, Migliorini\, and also Mauri\, concerning the effective decomposition theorem for the Hitchin morphism involving Ngo strings. This is all based on various discussions with Ben Davison. \nZoom (635 7328 0984\, Kenncode: kleinste sechsstellige Primzahl)

SUMMARY:International Seminar on Automorphic Forms
DESCRIPTION:Zheng Liu (UCSB): Yoshida lifts and congruences\nA Yoshida lift is the theta lift of two modular forms to GSp(4). Its congruence with stable forms on GSp(4) can be used to produce a lower bound on the Selmer group of the Rankin-Selberg product of the two modular forms. We study this congruence by using Rallis inner product formula\, Bessel periods and Furusawa’s pullback formula\, together with p-adic interpolation. \nZoom (680 4828 0736\, The password is the first Fourier coefficient of the modular j-function (as digits)).

SUMMARY:Oberseminar Algebra und Geometrie
DESCRIPTION:Konstantinos Kartas (Universität Münster): Taming perfectoid algebras \nAbstract: The almost purity theorem is a foundational result in perfectoid geometry which\, as the name suggests\, holds only in an “almost” sense. We aim to identify a class of rings for which the theorem holds in a genuine (non-almost) form. Joint work in progress with Franziska Jahnke. \n  \n

SUMMARY:Kolloquium Geometrie und Arithmetik
DESCRIPTION:Niklas Kipp (Paris-Saclay): A solid Syntomification \nAbstract: We will learn a strategy to obtain a well behaved six-functor formalism for Syntomic cohomology of p-adic formal schemes as defined by Bhatt-Morrow-Scholze. Here well behaved mainly refers to this six-functor formalism generalising Poincaré duality (which was proven by Longke Tang in the smooth and proper case) to smooth morphisms using a version of compactly supported syntomic cohomology. Concretely\, we will recall some aspects of the stacky approach to Prismatic/Syntomic cohomology (following Bhatt-Lurie and Drinfeld) as well as some aspects of the theory of (Solid) analytic stacks (following Clausen-Scholze). \n  \n
