SUMMARY:Integral Nori Motives
DESCRIPTION:Swann Tubach (ENS Lyon) \nThe classical theory of Nori motives provides a tensor abelian category of motives over a field k of characteristic zero\, with a nice universal property and realisation functors interpolating various cohomology theories. We will construct a commutative algebra N_X in the category of étale motivic sheaves over any scheme X of characteristic zero\, compatible with base change\, such that the category DNgm(X) of geometric objects in modules over N_X has natural t-structures\, the 6 operations\, and conservative realisation functors. Over a field we recover the derived category of Nori motives\, and with rational coefficients we recover the derived category of Ivorra-Morel’s category of perverse Nori motives. This provides abelian categories of motivic sheaves with integral coefficients. This is joint work with Raphaël Ruimy.

SUMMARY:Berthelot's conjecture via p-adic homotopy theory
DESCRIPTION:Alberto Vezzani (Universitá degli Studi di Milano) \nAbstract: By drawing parallels to classical work by Monsky-Washnitzer\, Elkik\, Arabia and others\, we motivate the study of (non-archimedean) motivic homotopy theory by showing that it can be used to define/re-define rational p-adic cohomology theories and prove new results about them. For example\, we show how to define relative rigid cohomology and deduce finiteness properties for it (joint work with V. Ertl)\, solving a version of a conjecture by Berthelot for coefficients of geometric origin.

SUMMARY:Rigid cocycles for SL(n) and their values at special points
DESCRIPTION:International Seminar on Automorphic Forms \nMarti Roset Julia (McGill University) Rigid cocycles for SL(n) and their values at special points \nThe theory of complex multiplication implies that the values of modular functions at CM points belong to abelian extensions of imaginary quadratic fields. In this talk\, we propose a conjectural extension of this phenomenon to the setting of totally real fields. Generalizing the work of Darmon\, Pozzi\, and Vonk\, we construct rigid cocycles for SL(n)\, which play the role of modular functions\, and define their values at points associated with totally real fields. The construction of these cocycles originates from a topological source: the Eisenstein class of a torus bundle. This is ongoing joint work with Peter Xu. \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits)

SUMMARY:Construction of Gaussian test functions
DESCRIPTION:International Seminar on Automorphic Forms \nAndreas Mihatsch (Zhejiang University) \nConstruction of Gaussian test functions \nThe relative trace formula comparison of Jacquet–Rallis relates two trace formulas: one for general linear groups and one for unitary groups. In this context\, one considers the transfer of test functions between the two sides. At the archimedean place\, the Gaussian for the positive definite unitary group provides a distinguished test function that often comes up in arithmetic settings. Accordingly\, it is of interest to understand its transfers to the general linear side. In my talk\, I will explain a direct construction of such transfers which is based on Kudla–Millson theory. This is joint work with Siddarth Sankaran and Tonghai Yang. \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits)

SUMMARY:The arithmetic of Fourier coefficients of Gan-Gurevich lifts on G2
DESCRIPTION:International Seminar on Automorphic Forms \nNaomi Sweeting (Princeton University) \nThe arithmetic of Fourier coefficients of Gan-Gurevich lifts on G2 \nThe arithmetic of Fourier coefficients of Gan-Gurevich lifts on G2 Abstract: Modular forms on exceptional groups carry a surprisingly rich arithmetic structure. For instance\, modular forms on G2 have a theory of Fourier expansions\, in which the coefficients are indexed by cubic rings (e.g. rings of integers in cubic field extensions of Q). This talk is about the Gan-Gurevich lifts\, which are modular forms on G2 arising by Langlands functoriality from classical modular forms on PGL2. Gross conjectured in 2000 that the norm squared of the Fourier coefficients of a Gan-Gurevich lift encode the cubic-twisted L values of the corresponding classical cusp form (echoing Waldspurger’s work on Fourier coefficients of half-integral weight modular forms). We prove this conjecture for a large class of Gan-Gurevich lifts coming from CM forms\, thus giving the first complete examples of Gross’s conjecture. Based on joint work in progress with Petar Bakic\, Alex Horawa\, and Siyan Daniel Li-Huerta. \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits)

SUMMARY:Critical values of Hecke L-funktions
DESCRIPTION:Han-Ung Kufner (Universität Regensburg) \nA conjecture of Deligne from 1977 relates the critical values of a motivic\nL-function with certain periods of the motive. The goal of this talk is to\nexplain Deligne’s conjecture and to discuss a proof in the case of Hecke\nL-functions. This generalizes a result of Blasius for Hecke characters of CMfields.\nFor the proof we use the recently constructed Eisenstein-Kronecker\nclasses of Kings-Sprang and combine them with ideas from Blasius’ proof.\n1

SUMMARY:Quantitative level lowering for modular forms
DESCRIPTION:Quantitative level lowering for modular forms \nMohamed Moakher (University of Pittsburgh) \nGiven a Hilbert modular form f of weight two over a totally real field F\, we can associate to it a finite module Phi(f) known as the congruence module for f\, which measures the congruences that f satisfies with other forms. When f is transferred to a quaternionic modular form f_D over a quaternion algebra D via the Jacquet-Langlands correspondence\, we can similarly define a congruence module Phi(f_D) for f_D. Pollack and Weston proposed a quantitative relationship between the sizes of Phi(f) and Phi(f_D)\, expressed in terms of invariants associated to f and D. In this talk\, I will outline the ideas underlying the proof of this relationship. The approach combines a method of Ribet and Takahashi with new techniques introduced by Böckle\, Khare\, and Manning.

SUMMARY:Seminar on Arithmetic Geometry
DESCRIPTION:Emanuel Reinecke (IHES): Poincare duality for proper morphisms in rigid geometry \nWhile the Z/p-etale cohomology of rigid-analytic varieties is in general hard to control\, it becomes more tractable when the varieties are proper. In my talk\, I will explain a relative Poincare duality statement for etale cohomology with finite coefficients which applies to any proper morphism of rigid-analytic varieties over nonarchimedean fields of mixed characteristic\, confirming an expectation of Bhatt-Hansen. A key ingredient in the proof will be a construction of trace maps for proper morphisms. Joint work with Shizhang Li and Bogdan Zavyalov. \nZoom (635 7328 0984\, Kenncode: kleinste sechsstellige Primzahl
