SUMMARY:Isotropic motivic homotopy theory
DESCRIPTION:Seminar on Arithmetic Geometry \nIn this talk I will introduce isotropic motivic homotopy theory\, which is a localization of the usual motivic homotopy theory obtained\, roughly speaking\, by “killing” anisotropic varieties. First\, I will present the triangulated category of isotropic motives\, constructed by Vishik\, as well as its stable homotopic counterpart. Then\, I will discuss the structure of the category of isotropic cellular spectra\, which are deeply related to comodules over the classical dual Steenrod algebra. \nZoom (Meeting-ID: 635 7328 0984\, Password: smallest six digit prime) \nFabio Tanania\, LMU München

SUMMARY:Quadratically enriched tropical intersections 1
DESCRIPTION:TGiZ-Seminar: Tropical geometry in Zoom (First meeting Winter Semester 2022/23) \nSabrina Pauli (Universität Duisburg-Essen) \nAbstract:\nTropical geometry has been proven to be a powerful computational tool in enumerative geometry over the complex and real numbers. Results from motivic homotopy theory allow to study questions in enumerative geometry over an arbitrary field k. In these two talks we present one of the first examples of how to use tropical geometry for questions in enuemrative geometry over k\, namely a proof of the quadratically enriched Bézout’s theorem for tropical curves. \nIn the first talk we explain what we mean by the “quadratic enrichment”\, that is we define the necessary notions of enumerative geometry over arbitrary fields valued in the Grothendieck-Witt ring of quadratic forms over k.

SUMMARY:Limit periods on curves and arithmetic heights
DESCRIPTION:Emre Sertöz (Hannover) \nWe show that in a nodal degeneration of smooth curves\, the periods of the resulting limit mixed Hodge structure (LMHS) contain arithmetic information. For instance\, if the nodal fiber is identified with a smooth curve C glued at two points p and q then the LMHS relates to the Neron–Tate height of p-q in the Jacobian of C. This observation combines an idea resembling “arithmetic deformation to the normal cone” with a study of the divergence behavior of the periods of a degenerating family of curves. Joint work with Robin de Jong and Spencer Bloch.

SUMMARY:P=W phenomena on singular moduli spaces
DESCRIPTION:Oberseminar Algebra und Geometrie \nCamilla Felisetti (University of Modena) \nAbstract:\nIrreducible holomorphic symplectic (IHS) varieties can be thought as a generalization of hyperkähler manifolds allowing singularities.\nAmong them we can find for example moduli spaces of sheaves on K3 and abelian surfaces\, which have been recently shown to play a crucial role in non abelian Hodge theory.\nAfter recalling the main features of IHS varieties\, I will present several results concerning their intersection cohomology and the perverse filtration associated with a Lagrangian fibration\, establishing a compact analogue of the celebrated P=W conjecture by de Cataldo\, Hausel and Migliorini for varieties which admit a symplectic resolution.\nThe talk is based on joint works with Mirko Mauri\, Junliang Shen and Qizheng Yin.

SUMMARY:Orthogonal modular forms\, Siegel modular forms and Eisenstein congruences
DESCRIPTION:International Seminar on Automorphic Forms \nThe theta correspondence between the orthogonal group and the symplectic group  provides a cornerstone for studying Siegel modular forms via orthogonal modular forms. In this work\, we make this correspondence completely explicit\, with precise level structure for low to moderate even rank and nontrivial discriminant. Guided by computational discoveries\, we prove congruences between eigenvalues of classical modular forms and eigenvalues of genuine Siegel modular forms\, obtain formulas for the number of neighbors in terms of eigenvalues of classical modular forms\, and formulate some conjectures that arise naturally from the data. This is joint work with Dan Fretwell\, Colin Ingalls\, Adam Logan\, Spencer Secord\, and John Voight \nEran Assaf (Dartmouth College) \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:Algebraicity of Higher Green Functions at a CM Point
DESCRIPTION:Yingkun Li (Darmstadt/Mainz) \nAbstract: By the classical theory of complex multiplication\, the modular j-function takes algebraic values at CM points. It is an interesting question to ask about the algebraic nature of other types of automorphic functions at CM points. For the automorphic Green function at integral parameters\, Gross and Zagier conjectured in the 1980s that their valuesat a CM point is essentially the logarithm of an algebraic number. In this talk\, we will discuss recent progress toward this conjecture. This is partly joint with Jan Bruinier and Tonghai Yang.

SUMMARY:Modularity and automorphy of cycles on Shimura varieties
DESCRIPTION:Congling Qiu (Yale University):  \nAlgebraic cycles are central objects in algebraic/arithmetic geometry and problems around them are very difficult. For Shimura varieties modularity of generating series with coefficients being algebraic cycles has been proved useful in the of study of algebraic cycles. A closely related problem is the automorphy of representations spanned by algebraic cycles. I will discuss the history of these problems some progress and applications. \nInternational Seminar on Automorphic Forms \nYou can join the Zoom meeting at \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits).

More precisely\, cover [DHKM20\, §A.1\,§A.2]. Then recall some background on GIT quotients\, and explain the relation between the GIT quotient and the sheaf quotient of moduli of cocycles [DHKM20\, §A.3]. \nJudith Ludwig (University Heidelberg) \nZoom: \nMeeting-ID: 61220727363 \nPassword: largest six digit prime

SUMMARY:On the Drinfeld's Lemma for the pro-étale fundamental group
DESCRIPTION:Seminar on Arithmetic Geometry: \nMarcin Lara (Goethe University) \nDrinfeld’s Lemma for the étale fundamental group serves as a replacement for the Künneth formula in positive characteristic\, that holds even when neither of the varieties is proper. I will report on the progress towards extending this result to the pro-étale fundamental group of Bhatt-Scholze. Note: this is still quite an early stage of the project.

SUMMARY:Integral p-adic cohomology for open and singular varieties
DESCRIPTION:Veronika Ertl (Universität Regensburg) \nIn this talk I will explain a joint result with Johannes Sprang and Atsushi Shiho. Under certain conditions of resolutions of singularities in positive characteristic\, we construct a “good” integral p-adic cohomology theory for open and singular varieties\, by using a version of Voevodsky’s h-topology. I will explain the construction and clarify in which sense our cohomology is a “good” p-adic cohomology theory. I will also touch on the question why a similar approach does not work in full generality without resolutions of singularities. \nlivestream:\nhttp://129.206.106.240/UzPL29kB/mathematikon-seminarraum.html

SUMMARY:Canonical integral models for Shimura varieties defined by tori
DESCRIPTION:Patrick Daniels (University of Michigan) \nPappas and Rapoport have recently shown that a p-adic integral model for Shimura variety  with parahoric level structure is characterized by the existence of a universal shtuka\, and they conjecture the existence of such a canonical integral model in general. We will illustrate the conjecture in the case of a Shimura variety defined by a torus\, where (surprisingly)\, the theory is already nontrivial. We will also explain how prismatic F-crystals arise naturally when constructing the universal shtuka in the torus case. \nMeeting-ID: 635 7328 0984\nPassword: smallest six digit prime

SUMMARY:Non-abelian Chabauty for the thrice-punctured line and the Selmer section conjecture
DESCRIPTION:Martin Lüdtke (Reichsuniversität Groningen) \nFor a smooth projective hyperbolic curve over a number field K the set of rational points X(K) is finite by Faltings’ Theorem. Grothendieck’s section conjecture predicts that this set can be described via Galois sections of the étale fundamental group of X. On the other hand\, the non-abelian Chabauty method produces p-adic analytic functions which conjecturally cut out X(K) as a subset of X(Qp). We relate the two conjectures and discuss the example of the thrice-punctured line\, where non-abelian Chabauty is used to prove a local-to-glocal principle for the section conjecture. \nlivestream:\nhttp://129.206.106.240/UzPL29kB/mathematikon-seminarraum.html

SUMMARY:International Seminar on Automorphic Forms: The invariants of the Weil representation of SL_2(Z)
DESCRIPTION:The transformation behaviour of the vector valued theta function of a positive definite even lattice under the metaplectic group Mp_2(Z) is described by the Weil representation. This representation plays an important role in the theory of automorphic forms. We show that its invariants are induced from 5 fundamental invariants. \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:"Classifying" fake projective planes
DESCRIPTION:Matthew Stover (Temple University) \nAbstract: \n A fake projective plane is a smooth complex projective surface with the same \ncomplex cohomology as the projective plane. I will describe several more refined \n"classifications"\, starting with the very vague "they are ball quotients"\, describing \na shorter proof (with shortcut via work of Esnault-Groechenig) of Klingler's theorem \nthat the associated lattice in PU(2\,1) is arithmetic\, and ending with my recent proof \nthat there are exactly 46 up to the action of Aut(C) (equivalently\, isomorphism of \nétale fundamental group). \nOberseminar Algebra und Geometrie \nZoom\nmeeting-ID: 635 5834 1373\npassword: the number of fake projective planes up to biholomorphism (read wikipedia carefully)
