SUMMARY:The combinatorics of the Brill-Noether Theory of general covers
DESCRIPTION:TGiZ-Seminar: Tropical geometry in Zoom (Second meeting Summer Semester 2022) \nKaelin Cook-Powell (Emory University) \nAbstract:\nThe study of line bundles on algebraic curves has historically had deep connections with combinatorics. For example\, standard young tableaux have been used to study line bundles of sufficiently general curves. Recently a variation of tableaux\, known as k-uniform displacement tableaux\, have been used to study line bundles of general covers — that is curves general in the Hurwitz space. We will discuss how these displacement tableaux relate to line bundles of general covers and examine how they are used to produce new results in Brill-Noether Theory.

SUMMARY:Brill-Noether Theory over the Hurwitz Space
DESCRIPTION:TGiZ-Seminar: Tropical geometry in Zoom (Second meeting Summer Semester 2022) \nDave Jensen (University of Kentucky) \nAbstract:\nBrill-Noether theory is the study of line bundles on algebraic curves. A series of results in the 80’s describe the varieties parameterizing line bundles with given invariants on a sufficiently general curve. More recently\, several mathematicians have turned their attention to the Brill-Noether theory of general covers — that is\, curves that are general in the Hurwitz space rather than in the moduli space of curves. We will survey these recent results and\, time permitting\, some generalizations.

SUMMARY:International Seminar on Automorphic Forms
DESCRIPTION:Determination of modular forms is one of the fundamental and interesting problems in number theory. It is known that if the Hecke eigenvalues of two newforms agree for all but finitely many primes\, then both the forms are the same. In other words\, the set of Hecke eigenvalues at primes determines the newform uniquely and this result is known as the multiplicity one theorem. In the case of Siegel cuspidal eigenforms of degree two\, the multiplicity one theorem has been proved only recently in 2018 by Schmidt. In this talk\, we refine the result of Schmidt by showing that if the Hecke eigenvalues of two Siegel eigenforms of level 1 agree at a set of primes of positive density\, then the eigenforms are the same (up to a constant). We also distinguish Siegel eigenforms from the signs of their Hecke eigenvalues. The main ingredient to prove these results are Galois representations attached to Siegel eigenforms\, the Chebotarev density theorem and some analytic properties of associated L-functions.

SUMMARY:Invariant rings of reductive representations and singularities of the Minimal Model Program
DESCRIPTION:Oberseminar Algebra und Geometrie \nDaniel Greb (Univ. Duisburg-Essen) \nAbstract:\nI will discuss my recent work with Braun\, Langlois\, and Moraga showing that invariant rings of finite-dimensional representations of (linearly) reductive groups over an algebraically closed field of characteristic zero have Kawamata log-terminal (klt) singularities. I will spend most of the time on explaining what klt singularities are\, why the klt condition is a very natural and geometric condition\, and why smaller classes of singularities are not sufficient in order to understand arbitrary reductive quotient singularities. Then\, I will discuss some applications of the main result\, e.g. to varieties important in geometric representation theory and to certain moduli spaces. If time permits\, I will discuss some ideas of the proof.

SUMMARY:International Seminar on Automorphic Forms
DESCRIPTION:We define a L-series for harmonic Maass forms and discuss their functional equations. A converse theorem for these L-series is given. As an application\, we interpret as proper values of our L-functions certain important quantities that arose in works by Bruinier-Funke-Imamoglu and Alfes-Schwagenscheidt\, and which they had philosophically viewed as “central L-values”. This is joint work with M. Lee\, W. Raji and L. Rolen.

SUMMARY:δ-Forms and Intersection Numbers
DESCRIPTION:Oberseminar Algebra und Geometrie \nAndreas Mihatsch (Universität Bonn) \n\nAbstract:\nδ-Forms were invented by Gubler–Künnemann\, they are certain\nhybrid objects on non-archimedean spaces that combine the smooth\ndifferential forms of Chambert-Loir–Ducros with tropical intersection\ntheory. In this talk\, I will first present a purely local definition of\nδ-forms that is based on the combinatorics of skeletons in Berkovich\nspaces. I will then explain an application to intersection numbers on\nintegral models: The lengths of artinian complete intersections on the\nmodel agree with certain integrals of δ-forms in the generic fiber.

SUMMARY:International Seminar on Automorphic Forms
DESCRIPTION:Sato-Tate conjecture in arithmetic progressions for certain families of elliptic curves \nIn this talk we will study moments of the trace of Frobenius of elliptic curves if the trace is restricted to a fixed arithmetic progression. In conclusion\, we will obtain the Sato-Tate distribution for the trace of certain families of Elliptic curves. As a special case we will recover a result of Birch proving Sato-Tate distribution for certain family of elliptic curves. Moreover\, we will see that these results follow from asymptotic formulas relating sums and moments of Hurwitz class numbers where the sums are restricted to certain arithmetic progressions. This is a joint work with Kathrin Bringmann and Ben Kane.

SUMMARY:Chern-Weil theory and Hilbert-Samuel theorem for semi-positive singular toroidal metrics on line bundles
DESCRIPTION:TGiZ-Seminar: Tropical geometry in Zoom (First meeting Summer Semester 2022) \nJosé Ignacio Burgos Gil (ICMAT\, Madrid) \nAbstract:\nIn this talk I will report on joint work with A. Botero\, D. Holmes and R. de Jong. Using the theory of b-divisors and non-pluripolar products we show that Chen-Weil theory and a Hilbert Samuel theorem can be extended to a wide class of singular semi-positive metrics. We apply the techniques relating semipositive metrics on line bundles to b-divisors to study the line bundle of Siegel-Jacobi forms with the Peterson metric. On the one hand we prove that the ring of Siegel-Jacobi forms of constant positive relative index is never finitely generated\, and we recover a formula of Tai giving the asymptotic growth of the dimension of the spaces of Siegel-Jacobi modular forms.

SUMMARY:Toroidal b-divisors and Monge-Ampère measures
DESCRIPTION:TGiZ-Seminar: Tropical geometry in Zoom (First meeting Summer Semester 2022) \nAna María Botero (Regensburg University) \nAbstract:\nA b-divisor on a smooth projective algebraic variety X is an element in the projective limit of divisors\, indexed over all smooth proper modifications of X\, and satisfying some functoriality properties. Amongst all b-divisors\, the so-called “toroidal” ones can be studied using convex-geometrical and tropical techniques. The aim of the talk is to give an overview of the theory. This joint work with Jose Burgos and Martin Sombra.

SUMMARY:Integral models of local Shimura varieties
DESCRIPTION:Abstract: Let $p$ be a prime number. Let $(G\, b\, \mu)$ be a local Shimura datum and $\CG$ be a quasi-parahoric group scheme for $G$ (these terms will be explained in the talk). Scholze has defined a functor on the category of perfectoid spaces in characteristic $p$ and has conjectured that this functor is representable by a formal scheme. I will explain the proof of this conjecture for classical groups. The conjecture also gives a group-theoretical interpretation of Rapoport-Zink spaces. This is joint work with G. Pappas. \nMeeting-ID: 635 7328 0984\nPassword: Smallest six digit prime number
