SUMMARY:Counting non-tempered automorphic forms using endoscopy
DESCRIPTION:International Seminar on Automorphic Forms \nAbstract: \nHow many automorphic representations of level n have a specified local factor at the infinite places? When this local factor is a discrete series representation\, this question is asymptotically well-undersertood as n grows. Non-tempered local factors\, on the other hand\, violate the Ramanujan conjecture and should be very rare. We use the endoscopic classification for representations to quantify this rarity in the case of cohomological representations of unitary groups\, and discuss some applications to the growth of cohomology of Shimura varieties. \nMathilde Gerbelli-Gauthier (McGill 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:A tropical Monge-Ampere equation and the SYZ conjecture
DESCRIPTION:TGiF-Seminar: Tropical geometry in Frankfurt (Second meeting Summer Semester 2023) \nMattias Jonsson (University of Michigan) \nAbstract: \nA celebrated result of Yau says that every compact Kähler manifold with trivial canonical bundle admits a Ricci flat metric in any given Kähler class. The proof amounts to solving a complex Monge-Ampère equation. I will discuss joint work with Hultgren\, Mazzon\, and McCleerey\, where we solve a “tropical” Monge–Ampère equation\, on the boundary of simplex. Through recent work of Yang Li\, this has applications to the SYZ conjecture\, on degenerations of Calabi-Yau manifolds. \n

SUMMARY:From amoebas to arithmetics
DESCRIPTION:TGiF-Seminar: Tropical geometry in Frankfurt (Second meeting Summer Semester 2023) \nRoberto Gualdi (Regensburg) \nAbstract: \nMotivated by the computation of the integral of a piecewise linear func- tion on the amoeba of the line (x1 + x2 + 1 = 0)\, we will show how tropical objects play a role in arithmetics. \nThis will bring us to an excursion into the Arakelov geometry of toric varieties; in this framework\, we will use our tropical computation to predict the arithmetic complexity of the intersection of a projective planar line with its translate by a torsion point. This is a joint work with Martín Sombra. \n

SUMMARY:Algebraicity of critical Hecke L-values
DESCRIPTION:Oberseminar Algebra und Geometrie \nJohannes Sprang (Universität Duisburg-Essen) \nAbstract: Euler’s beautiful formula on the values of the Riemann zeta function at the positive even integers can be seen as the starting point of the investigation of special values of L-functions. In particular\, Euler’s result shows that all critical zeta values are rational up to multiplication with a particular period\, here the period is a power of 2πi. Conjecturally this is expected to hold for all critical L-values of motives. In this talk\, I will explain a joint result with Guido Kings on the algebraicity of critical Hecke L-values up to explicit periods for totally imaginary fields.

SUMMARY:A general view on multiple zeta values\, modular forms and related q-series
DESCRIPTION:International Seminar on Automorphic Forms \nAnnika Burmester (Bielefeld University) \nMultiple zeta values and modular forms have a deep\, partly mysterious\, connection. This can be seen in the Broadhurst-Kreimer conjecture\, which was made partly explicit by Gangl-Kaneko-Zagier in 2006. Further\, multiple zeta values occur in the Fourier expansion of multiple Eisenstein series as computed by Bachmann. We will study this connection in more details on a formal level. This means\, we review formal multiple zeta values and then introduce the algebra G^f\, which should be seen as a formal version of multiple Eisenstein series\, and also multiple q-zeta values and polynomial functions on partitions simultaneously. We will give a surjective algebra morphism from G^f into the algebra of formal multiple zeta values. \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:Local Weight-Monodromy Conjecture
DESCRIPTION:Seminar: Non-archimedean geometry \nBogdan Zavyalov \nAbstract: Let X be a smooth and proper variety over a local field K. Then the weight-monodromy conjecture predicts that the monodromy and weight filtrations coincide up to a shift. Recently\, P. Scholze proved this conjecture for set-theoretic complete intersections inside the projective space using the theory of perfectoid spaces. Alternatively\, one can formulate a (local) version of the weight-monodromy conjecture for the nearby cycles. We will give a precise formulation of this conjecture and prove it in some cases following the strategy of Scholze in the global case. This is joint work with David Hansen.

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.
