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: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

SUMMARY:Membranes and Maps
DESCRIPTION:In joint work with A. Brini\, it was conjectured that equivariant Gromov–Witten invariants of Calabi–Yau fivefolds are governed by so-called membrane indices. When the fivefold is a product of a Calabi–Yau threefold and the affine plane\, the latter invariants agree with\, or refine\, Gopakumar–Vafa invariants. I will present evidence for the conjecture. Moreover\, I will explain how the numerical correspondence informs us about a possible modular interpretation of M2-branes since ultimately their moduli space should give rise to membrane indices. Building on ideas of Nekrasov and Okounkov\, I will propose a geometric interpretation of M2-branes in some concrete situations. I will then translate this proposal into formulas for Hodge integrals\, which can be verified in certain limits. This is based on work in progress with A. Giacchetto and R. Pandharipande.

SUMMARY:Seminar on Arithmetic Geometry
DESCRIPTION:Manuel Hoff (Bielefeld): Sheared displays and p-divisible groups \nAbstract: Let p be a prime and let R be a p-nilpotent ring. The theory of displays\, as developed by Zink and Lau\, gives an equivalence between infinitesimal p-divisible groups and V-nilpotent displays over R. The aim of the talk is to explain that general p-divisible groups are equivalent to sheared displays\, the analogue of displays where the ring of Witt vectors is replaced by its sheared version. This is joint work with Eike Lau. \nZoom (635 7328 0984\, Kenncode: kleinste sechsstellige Primzahl)

SUMMARY:de Rham-Witt Complex
DESCRIPTION:Anton Engelmann \nDerived considerations \nThe Nygaard filtration and foundations for the last four talks. Define filtered derived categories (Construction 8.4.1) and the Beilinson t-structure (Remark 8.4.8). Use Proposition 8.4.10 as a definition for the functor Lηp\, and give a more explicit description relating it to the functor ηp of §2.1. Discuss Proposition 7.2.4\, Theorem 7.4.7 and Corollary 7.4.8. Finally\, define the Nygaard filtration as in Proposition 8.4.11. As time permits\, come back to some descriptions and properties in §8.1 and §8.2.
