SUMMARY:Motivic monodromy and p-adic cohomology theories
DESCRIPTION:Martin Gallauer (University of Warwick) \nLimit structures in cohomology provide an indispensable tool in the study of varieties in families. This was brought to perfection in complex geometry and attempts have been made to transport it to arithmetic settings. In this talk I will introduce an approach to placing limit structures in all settings on an equal footing. It allows for a sharpening of this tool in p-adic cohomology. (Joint work with Federico Binda and Alberto Vezzani.)

SUMMARY:Geometric arcs and fundamental groups of rigid spaces
DESCRIPTION:Seminar: Non-archimedean geometry \nMarcin Lara \nAbstract: We introduce a new category of covering spaces in rigid geometry\, called geometric coverings\, and show it is classified by a certain topological fundamental group. Geometric coverings generalize the class of étale coverings\, introduced by de Jong\, and its various natural modifications\, and have certain desirable properties that were missing from those older notions: they are étale local and closed under taking infinite disjoint unions. The definition is based on the property of unique lifting of “geometric arcs.” On the way\, we answer some questions from the foundational paper of de Jong. This is joint work with Piotr Achinger and Alex Youcis.

SUMMARY:Tangent spaces in p-adic geometry
DESCRIPTION:Sean Howe (University of Utah) \nAbstract: In complex geometry\, it is an extremely useful fact that universal covers of complex manifolds have tangent spaces and that period maps arising from the cohomology of families of varieties are differentiable. In p-adic geometry\, unfortunately\, it is known that the covers of rigid analytic varieties trivializing local systems of etale cohomology do not admit a good theory of Kahler differentials. In this talk\, we explain how\, building from first principles and a single clever idea\, one can nonetheless assign tangent spaces to many of the perfectoid spaces and diamonds that arise naturally in the study of rigid analytic varieties and their cohomology and then differentiate period maps. These spaces provide\, in particular\, a natural conceptual framework for predicting when a diamond is a perfectoid space. In this talk we will focus mostly on examples in the theory of local Shimura varieties and explain the relation to work of Johannson\, Ludwig and Hansen on perfectoid quotients of Lubin-Tate space\, Ivanov and Weinstein on cohomological smoothness\, and Pan and Camargo on geometric Sen theory and sheaves of locally analytic functions. This is joint work with Peter Wear.

SUMMARY:Centers of F-purity and their behavior under finite covers
DESCRIPTION:Javier Carvajal-Rojas (Leuven) \nAbstract: Let X be an F -split variety (roughly\, a strong form of ordinary log Calabi—Yau variety) and Y /X be a finite cover such that the F -splitting of X lifts to Y . How do the spectra of centers of F -purity (roughly\, arithmetically tame log-canonical centers) of Y and X relate to one another? This turns out to be a very tricky question due to wild ramification. An optimal answer would look like Cohen—Seidenberg-type theorems for spectra of centers of F-purity. In this talk\, I will report on work in progress with A. Fayolle (U. of Utah) where we address this question. \n

SUMMARY:Mixed mock modularity of special divisors
DESCRIPTION:International Seminar on Automorphic Forms \nSalim Tayou (Harvard University) \nKudla-Millson and Borcherds have proved some time ago that the generating series of special divisors in orthogonal Shimura varieties are modular forms. In this talk\, I will explain an extension of these results to toroidal compactifications where we prove that the generating series is a mixed mock modular form. More precisely\, we find an explicit completion using theta series associated to rays in the cone decomposition. The proof relies on intersection theory at the boundary of the Shimura variety. This recovers and refines recent results of Bruinier and Zemel. The result of this talk are joint work with Philip Engel and Francois Greer. \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:Hodge--Tate crystals and p-adic non-abelian Hodge theory
DESCRIPTION:Seminar: Non-archimedean geometry \nYu Min \nAbstract: The coefficient theory of prismatic cohomology has been investigated a lot recently. For example\, Morrow–Tsuji and Tian have discovered the relationship between Hodge–Tate crystals and Higgs bundles (at least in the local case). In this talk\, I will briefly talk about how to get a global correspondence between Hodge–Tate crystals and Higgs bundles after inverting p. Then I will discuss what we can say without inverting p in the geometric case (over Oc) (if time permits\, also in the arithmetic case (over W(k))). This is joint work with Yupeng Wang.

SUMMARY:On the K-theory of Z/p^n
DESCRIPTION:Dr. Achim Krause (Universität Heidelberg) \nAbstract: Algebraic K-theory is an invariant of rings that is notoriously hard to compute\, especially in non-regular situations. For example\, Quillen computed the K-theory of finite fields already in 1972\, but the case of rings of the form Z/p^n for n>1 has been out of reach until now. In joint work with Antieau and Nikolaus\, we apply Prismatic Cohomology to this problem\, leading to both a practical algorithm to compute these groups\, as well as surprising results on their large-degree behaviour.

SUMMARY:Sen Operators and Lie Algebras arising from Galois Representations over p-adic Varieties
DESCRIPTION:Seminar: Non-archimedean geometry \nTongmu He \nAbstract: Any finite-dimensional p-adic representation of the absolute Galois group of a p-adic local field with imperfect residue field is characterized by its arithmetic and geometric Sen operators defined by Sen and Brinon. We generalize their construction to the fundamental group of a p-adic affine variety with a semi-stable chart\, and prove that the module of Sen operators is canonically defined\, independently of the choice of the chart. When the representation comes from a Qp-representation of the fundamental group\, we relate the infinitesimal action of inertia subgroups with Sen operators\, which is a generalization of a result of Sen and Ohkubo. These Sen operators can be extended continuously to certain infinite-dimensional representations. As an application\, we prove that the geometric Sen operators annihilate locally analytic vectors\, generalizing a result of Pan.

SUMMARY:Artin's primitive root conjecture: classically and over Fq[T]
DESCRIPTION:International Seminar on Automorphic Forms \nIn 1927\, E. Artin proposed a conjecture for the number of primes p ≤ x\, for which g generates (ℤ/pℤ)x. By observing numerical deviations from Artin’s originally predicted asymptotic\, Derrick and Emma Lehmer (1957) identified the need for an additional correction factor; leading to a modified conjecture that was eventually proved correct by Hooley (1967)\, under the assumption of the Generalized Riemann Hypothesis (GRH). In this talk we discuss several variants of Artin’s conjecture: namely an “Artin Twin Primes Conjecture”\, as well as an appropriate analogue of Artin’s primitive root conjecture for algebraic function fields. \nEzra Waxman (University of Haifa) \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:Torsion points of elliptic curves via Berkovich spaces over Z
DESCRIPTION:Seminar: Non-archimedean geometry \nJérôme Poineau \nAbstract: Berkovich spaces over Z may be seen as fibrations containing complex analytic spaces as well as p-adic analytic spaces\, for every prime number p. We will give an introduction to those spaces and explain how they may be used in an arithmetic context to prove height inequalities. As an application\, following a strategy by DeMarco-Krieger-Ye\, we will give a proof of a conjecture of Bogomolov-Fu-Tschinkel on uniform bounds on the number of common images on P^1 of torsion points of two elliptic curves.

SUMMARY:Vectorial Drinfeld modular forms over Tate algebras
DESCRIPTION:Oğuz Gezmiş: Hecke operators \nOur goal in the last talk is to study Hecke operators acting on the space of VDMFs and consequences of such an action for Drinfeld modular forms. In particular\, applying hyperderivatives and evaluating the coordinates of vectorial modular forms at roots of unity\, we will obtain Hecke eigenforms for certain congruence subgroups of GL2(A). We start with defining the slash operator and the Hecke operator Tp for each monic irreducible polynomial p in A. Later on\, we give the necessary ideas for the proof of [PP18\, Prop. 5.12\, Prop. 5.18] and briefly mention why the regularity condition is required for the stability of the space of VDMFs under Hecke operators [PP18\, Rem. 5.13]. We continue with giving some examples of Hecke eigenforms in our setting and analyze the behavior of vectorial Eisenstein series under Tp as well as provide a sketch of a proof for [PP18\, Cor. 5.23-5.24]. The main reference for the talk is [PP18\, §5–5.3].

SUMMARY:Intersections of components of Emerton-Gee stack for GL2
DESCRIPTION:Kalyani Kansal (Johns Hopkins University) \nAbstract: The Emerton-Gee stack for GL2 is a stack of (phi\, Gamma)-modules of rank two. Its reduced part\, X\, is an algebraic stack of finite type over a finite field\, and it can be viewed as a moduli stack of mod p representations of a p-adic Galois group. We compute criteria for codimension one intersections of the irreducible components of X. We interpret these criteria in terms of representation theory of GL2\, motivated by conjectural categorical p-adic and mod p Langlands correspondence. We also give a representation-theoretic cohomological criterion for the number of top-dimensional components in a codimension one intersection.

SUMMARY:Motivic homotopy theory beyond A^1-invariance
DESCRIPTION:Ryomei Iwasa (Paris) \nAbstract: The basic question I’d like to address in this talk is the following: How to do homotopy theory in algebraic geometry while keeping the affine line A^1 non-contractible? I will explain that tensor invertibility of the pointed projective line P^1 supplies homotopies between projective bundle sections in a non-trivial but canonical way. This dramatically expands the scope of motivic homotopy theory\, and non-A^1-invariant theories such as syntomic cohomology\, prismatic cohomology\, algebraic K-theory\, and topological cyclic homology can be studied from this perspective. In particular\, I’ll explain that algebraic and Selmer K-theory are described by Snaith-type formulas. Based on joint work with Toni Annala and Marc Hoyois.
