SUMMARY:Gan-Gross-Prasad cycles and derivatives of p-adic L-functions
DESCRIPTION:International Seminar on Automorphic Forms \nDaniel Disegni (Aix-Marseille University) \nCertain Rankin-Selberg motives of rank n(n+1) are endowed with algebraic cycles arising from maps of unitary Shimura varieties. Gan-Gross-Prasad conjectured that these cycles are analogous to Heegner points\, in the sense that their nontriviality should be detected by derivatives of L-functions.\nI will propose another nontriviality criterion\, based on p-adic L-functions. Under some local conditions\, this variant can be established in a refined quantitative form\, via the construction and comparison two p-adic relative-trace formulas. (Joint work with Wei Zhang.) \nhttps://tu-darmstadt.zoom.us/j/68048280736

SUMMARY:Density of rational points near manifolds
DESCRIPTION:Damaris Schindler (Universität Göttingen) \nGiven a bounded submanifold M in R^n\, how many rational points with common bounded denominator are there in a small thickening of M? Under what conditions can we count them asymptotically as the size of the denominator goes to infinity? I will discuss some recent work in this direction and arithmetic applications such as Serre’s dimension growth conjecture as well as applications in Diophantine approximation. For this I’ll focus on joint work with Shuntaro Yamagishi\, as well as joint work with Rajula Srivastava and Niclas Technau.

SUMMARY:Chowla-Selberg phenomenon over function fields
DESCRIPTION:International Seminar on Automorphic Forms \nFu-Tsun Wei (National Tsing Hua University) \nIn this talk\, I will first determine the algebraic relations among various special gamma values over function fields. The result is based on the intrinsic relations between gamma values in question and periods of CM dual t-motives\, which are interpreted in terms of their “distributions”. This enables us to express every “abelian” CM period by a suitable product of special gamma values (up to an algebraic multiple)\, and derive a Chowla–Selberg-type formula in the function field case. \nhttps://tu-darmstadt.zoom.us/j/68048280736

SUMMARY:Algebraic geometry of the classical Yang-Baxter equation
DESCRIPTION:Oberseminar Algebra und Geometrie \nIgor Burban  (Universität Paderborn) \nAbstract: \nClassical Yang-Baxter equation (CYBE) plays an important role in the modern theory of integrable systems. In a seminal work of Belavin and Drinfeld from the year 1983 it was proven that solutions of CYBE can have one of the following three types: elliptic\, trigonometric or rational. Moreover\, Belavin and Drinfeld gave a complete classification of all elliptic and trigonometric solutions. \nIn my talk\, I am going to explain a geometric description of solutions of (CYBE). Namely\, starting with any geometric datum (E\, A)\, where E is a Weierstraß cubic curve and A a torsion free sheaf of Lie algebras (whose generic fiber is a given complex simple Lie algebra) with vanishing cohomology\, one can associate to it in a canonical way a solution of CYBE. It turns out that all solutions of CYBE arise in this way. Moreover\, the type of the curve in the datum (E\, A) (i.e. smooth/nodal/cuspidal) determines the type of the corresponding solution of CYBE (i.e elliptic/trigonometric/rational).\nThe developed method will be illustrated by explicit examples. This talk is based on my joint works with Raschid Abedin\, Lennart Galinat and Thilo Henrich.

SUMMARY:The rhizomic topology and tropical abelian varieties
DESCRIPTION:Leo Herr (Universität Leiden) \nAbstract:\nThe log etale topology is a natural analogue of the etale topology for log schemes. Unfortunately\, very few things satisfy log etale descent — not even vector bundles or the structure sheaf. We introduce a new rhizomic topology that sits in between the usual and log etale topologies and show most things do satisfy rhizomic descent! As a case study\, we look at tropical abelian varieties and give some exotic examples.

SUMMARY:Isotropic motivic categories
DESCRIPTION:Fabio Tanania (TU Darmstadt) \nIn this talk\, I will introduce the isotropic stable motivic homotopy category\, which is a stable homotopic version of Vishik’s category of isotropic motives. These are local versions of the classical motivic categories SH(k) and DM(k)\, obtained roughly speaking by annihilating motives of anisotropic varieties. When the base field k is flexible\, then isotropic motivic categories have a lot of remarkable properties. As an example\, I will describe the structure of cellular isotropic spectra in terms of well-known objects coming from classical homotopy theory. Then\, I will discuss what is known about the non-cellular part of isotropic motivic categories and state some open questions.

SUMMARY:CRC-Colloquium
DESCRIPTION:15:20 Coffee (or earlier)\n15:30 – 16:30 Georg Tamme (Universität Mainz): Higher algebra and K-theory\n16:30 Coffee and Cake\n17:15 – 18:15 Otmar Venjakob (Universität Heidelberg): Explicit Reciprocity Laws in Number Theory\n18:45 Dinner \nAbstract G. Tamme:\nAlgebraic K-theory\, more precisely the group K_0(X) of a scheme X\, was first introduced by Grothendieck in order to formulate and prove a very general Riemann-Roch theorem. Subsequently\, lower (i.e. K_i for i<0) and higher (i.e. K_i for i>0) K-groups have been introduced by Bass\, Milnor\, Quillen\, and Thomason. They have turned out to be a rich invariant\, playing an important role in various fields such as number theory and topology. Although explicit computations of K-groups remain challenging\, modern methods from higher algebra and derived algebraic geometry have led to several breakthrough structural results concerning these groups. In the talk\, I will give an introduction to these topics and\, time permitting\, discuss some recent applications. \nAbstract O. Venjakob:\nThe quadratic Reciprocity Law for the Legendre or Jacobi-Symbol forms the starting point of all Reciprocity Laws as well as of class field theory. It is closely related to the product formula of the quadratic Hilbert-Symbol over local fields. Various mathematicians have established higher explicit formulae to compute higher Hilbert-Symbols. Analogs were found for formal (Lubin-Tate) groups. Eventually Perrin-Riou has formulated a Reciprocity Law\, which allows the explicit computation of local cup product pairings by means of Iwasawa- and p-adic Hodge Theory. In this talk I shall try to give an overview of these topics\, at the end I will explain recent developments in this regard.

SUMMARY:Zagier’s conjecture on polylogarithms: from function fields to number fields
DESCRIPTION:Quentin Gazda (CMLS Palaiseau) \nZagier’s conjecture is a certain formulation of the following slogan: linear relations among polylogarithms evaluated at algebraic numbers arise from relations between K-theory symbols. By identifying the different attributes of this conjecture\, one can state and prove a similar version in arithmetic of function fields. Classical polylogarithms are then replaced by those of Carlitz. The proof\, very different from the techniques developed so far\, uses ingredients from the theory of difference equations. It involves deformations of Carlitz polylogarithms where a new variable $t$ appears. This results from a joint work with A. Maurischat.\nWhile we currently lack the technology to reproduce this argument in number theory\, it is amusing to speculate on a hypothetical transcription. $q$-deformations of polylogarithms then replace these « $t$-deformations ». With T. Bouis\, we recently encountered versions of $q$-polylogarithms in the syntomic Chern class introduced by Bhatt-Lurie. This is encouraging…! I will mention these works in a second part of the presentation.

SUMMARY:Seminar on Arithmetic Geometry
DESCRIPTION:Minjia Zhang (Princeton University): Igusa stacks and cohomology of Shimura varieties \nShimura varieties have been playing an important role in the Langlands program. Recently\, following a conjecture of Peter Scholze\, we have constructed certain p-adic geometric objects\, which we call ​”Igusa stacks” (in the PEL type case)\, which encode prime-to-p information of Shimura varieties. Together with certain flag varieties (encoding information of Shimura varieties at p)\, they give p-adic uniformization of Shimura varieties. In this talk\, I will explain construction of Igusa stack for Hodge type Shimura varieties\, which leads to new proofs of Mantovan’s product formula\, Eichler-Shimura relations\, and vanishing type results about torsion cohomology of Shimura varieties. This is based on joint work with Patrick Daniels\, Daniel Kim and Pol van Hoften. \nZoom 635 7328 0984\, Kenncode: kleinste sechsstellige Primzahl

SUMMARY:On the denominators of the special values of the partial zeta functions of real quadratic fields
DESCRIPTION:International Seminar on Automorphic Forms \nHohto Bekki (MPIM Bonn) \nIt is classically known that the special values of the partial zeta functions of real quadratic fields\, or more generally\, of totally real fields at negative integers are rational numbers. In this talk\, I would like to discuss the denominators of these rational numbers in the case of real quadratic fields. More precisely\, Duke recently presented a conjecture which gives a universal upper bound for the denominators of these special values of the partial zeta functions of real quadratic fields. I would like to explain that by using Harder’s theory on the denominator of the Eisenstein class for SL(2\,Z)\, we can prove the conjecture of Duke and moreover the sharpness of his upper bound. This is a joint work with Ryotaro Sakamoto. \nhttps://tu-darmstadt.zoom.us/j/68048280736

SUMMARY:A gentle introduction to non-abelian Hodge and P=W conjecture
DESCRIPTION:Oberseminar Algebra und Geometrie \nAlexandre Minets (MPI Bonn) \nAbstract: \nTitle: A gentle introduction to non-abelian Hodge and P=W conjecture\nAbstract: Let C be a Riemann surface\, and M_B the character variety of C; in other words\, the points of M_B parameterise representations of the fundamental group of C. Up to a _non-algebraic_ homeomorphism\, M_B can also be realized as the variety M_H of algebraic vector bundles on C equipped with a twisted endomorphism (otherwise known as Higgs bundles). The P=W conjecture of de Cataldo-Hausel-Migliorini postulates that some algebraic data survives the homeomorphisms above; more precisely\, the number of F_q-points of M_B is controlled by an algebraic integrable system on M_H. I will give a gentle introduction to these objects\, focusing on one explicit example. If time permits\, I will sketch some ideas that went into our recent proof of P=W (joint with T. Hausel\, A. Mellit\, O. Schiffmann).
