SUMMARY:Kudla's conjecture in cohomology for unitary Shimura varieties
DESCRIPTION:International Seminar on Automorphic Forms \nFrançois Greer (Michigan State University): Kudla’s conjecture in cohomology for unitary Shimura varieties \nThe generating series for special cycles in a unitary Shimura variety $X$ associated to a Hermitian lattice of signature $(1\,n)$ is a modular form. Such a Shimura variety has a unique toroidal compactification\, and one can consider the closures of the special cycles there. We prove that for codimension up to the middle\, the generating series for these closures is quasi-modular\, and explain how to make boundary corrections to restore modularity\, answering a question of Kudla. This is based on joint work with Salim Ta \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits)

SUMMARY:Oberseminar Algebra und Geometrie
DESCRIPTION:Annalisa Grossi (Università di Bologna): In search of maximal branes on Hyper-Kähler manifolds \nAbstract: Given a holomorphic or anti-holomorphic involution on a complex variety\, the Smith-Thom inequality says that the total \mathbb{F}_2-Betti number of the fixed locus is no greater than the total \mathbb{F}_2-Betti number of the ambient variety. The involution is called maximal when the equality is achieved. On a Hyper-Kähler manifold X a holomorphic or a anti-holomorphic involution is referred to as a brane involution. While examples of non-compact hyper-Kähler manifolds admitting maximal branes are known\, the compact case is more intriguing. In particular\, although there exist some K3 surfaces admitting maximal brane involutions\, the main result that I will show you is the non-existence of maximal branes on Hyper-Kähler manifolds deformation equivalent to the Hilbert scheme of points on a K3 surface. This talk is based on a joint work and on a joint work in progress with S. Billi\, L. Fu and V. Kharlamov.

SUMMARY:Algebraicity of critical Hecke L-values
DESCRIPTION:Prof. Dr. Johannes Sprang (Universität Duisburg-Essen) \nEuler’s beautiful formula for 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.\nIn 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. As an application\, I will discuss the construction of p-adic L-functions for such fields. \n

SUMMARY:p-adic periods of 1-motives
DESCRIPTION:Felix Sefzig (Universität Zürich) \nI will present a new construction of the p-adic de Rham comparison isomorphism for 1-motives. As an application\, I will show how this approach leads to explicit computations of the periods of elliptic and hyperelliptic curves. In particular\, this provides concrete\, non-trivial examples of so-called motivic periods.

SUMMARY:Jacobi forms and modular differential equations
DESCRIPTION:International Seminar on Automorphic Forms \nDmitrii Adler (MPIM Bonn):  Jacobi forms and modular differential equations \nThe Serre derivative is a differential operator that raises the weight of a modular form by 2. One possible generalization of the Serre derivative to the setting of Jacobi forms is a modification of the heat operator involving the quasi-modular Eisenstein series E_2. In this talk\, I will present an approach to constructing modular differential equations for Jacobi forms with respect to this operator. This method makes it possible to describe solutions of first- and second-order modular differential equations (Kaneko–Zagier type equations)\, to construct higher-order differential equations\, and to obtain applications to the elliptic genus of Calabi–Yau manifolds. This is joint work with Valery Gritsenko. \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits)

SUMMARY:Jacobians with Complex Multiplication
DESCRIPTION:Ben Moonen (Radboud University Nijmegen) \nAn old conjecture by Coleman predicts that if we fix a sufficiently large integer g\, there exist only finitely many (smooth projective) complex curves of genus g whose Jacobians are abelian variety of CM type. Coleman originally conjectured this to be true for g>3; there are\, however\, counterexamples for g up to 7. I will explain how\, through a programme initiated by Oort\, this problem relates to the question of whether in the moduli space of abelian varieties there exists positive dimensional special subvarieties (Shimura varieties) that are contained in the Torelli locus. The goal of my talk is to explain what we currently know about this problem\, and what not.

SUMMARY:Sums of Hecke eigenvalues along polynomials and arithmetic applications
DESCRIPTION:International Seminar on Automorphic Forms \nKaty Woo (Stanford University): Sums of Hecke eigenvalues along polynomials and arithmetic applications \nWe study sums of absolute values of Hecke eigenvalues of GL(2) representations that are tempered at all finite places. We show that these sums exhibit logarithmic savings over the trivial bound if and only if the representation is cuspidal. Further\, we connect the problem of studying the sums of Hecke eigenvalues along polynomial values to the base change problem for GL(2). Finally\, we will describe some arithmetic applications of bounds on these sums for counting rational points on del Pezzo surfaces. \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits)

SUMMARY:Seminar on Arithmetic Geometry
DESCRIPTION:Luca Marannino (Jussieu)\, On anticyclotomic twists of modular forms at inert primes \nIn this talk\, we outline an approach to the study of anticyclotomic twists of modular forms\, when the fixed prime p is inert in the relevant quadratic imaginary field. After revisiting old (and less old) results involving Heegner points/cycles\, we will focus on our recent work. Following ideas of Castella-Do for the “p split” case\, one can envisage a construction of an anticyclotomic Euler system arising from a suitable manipulation of diagonal classes on a triple product of modular curves and obtain new p-adic evidence for the Bloch-Kato conjecture in rank 1 situations. \nZoom (635 7328 0984\, Kenncode: kleinste sechsstellige Primzahl)
