SUMMARY:The Logarithmic Hilbert Scheme and its Tropicalisation
DESCRIPTION:Oberseminar Algebra und Geometrie \nPatrick Kennedy-Hunt (University of Cambridge) \n\nAbstract: Let X be a scheme equipped with a SNC divisor D. I will sketch the construction of a proper moduli space of subschemes Z in expansions of X such that Z satisfies an appropriate transversality condition to D. The central insight is a tropical understanding for when Z is flat over the Artin fan of X\, and how this behaves in families. I will present the example of the logarithmic linear system\, a toric modification of projective space. The associated fan is closely related to the geometry of tropical curves and secondary polytopes. Joint work with Dhruv Ranganathan.

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

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: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: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.
