SUMMARY:Regular subdivisions and bounds on initial ideals
DESCRIPTION:TGiF-Seminar: Tropical geometry in Frankfurt (Second meeting Winter Semester 2024/25) \nGeorge Balla (TU Berlin)\nAbstract: We extend two known constructions that relate regular subdivisions to initial degenerations of projective toric varieties and Grassmannians. We associate a point configuration A with any homogeneous ideal I. We obtain upper and lower bounds on each initial ideal of I in terms of regular subdivisions of A. We also investigate when these bounds are exact\, for example\, the lower bound is exact for every initial ideal of the Plücker ideal I(2\,n) with respect to points in the tropicalization. This talk is based on joint work with Dan Corey\, Igor Makhlin\, and Victoria Schleis.

DESCRIPTION:Milton Lin (Johns Hopkins University): Geometric Casselman-Shalika in mixed characteristic \nI will present joint work with Ashwin Iyengar and Konrad Zou\, where we proved a geometric analog of the (local) Casselman-Shalika formula for split connected reductive groups over mixed characteristic local fields. This formula captures properties of Fourier coefficients of automorphic functions that are fundamental to the Langlands correspondence. \nZoom (635 7328 0984\, Kenncode: kleinste sechsstellige Primzahl

SUMMARY:Moduli spaces of twisted maps to smooth pairs
DESCRIPTION:TGiF-Seminar: Tropical geometry in Frankfurt (Second meeting Winter Semester 2024/25) \nRobert Crumplin (Universität Heidelberg)\n\nAbstract: The question of counting maps from marked curves with fixed tangency conditions to a divisor in the target has been studied extensively over the past 15 years. One way of formulating these enumerative problems is via twisted maps to a root stack. I will describe the geometry of moduli spaces of twisted maps using tropical techniques\, in particular giving new understanding to universal structural results of orbifold Gromov–Witten invariants. If time permits\, I will talk about upcoming work with Sam Johnston which relates these moduli spaces to their logarithmic counterparts and provides a splitting of the virtual class in terms of the aforementioned tropical data.

DESCRIPTION:Jonas Stelzig (LMU München / JGU Mainz) \nAbstract: I will introduce\, and survey the context of\, ABC triple Massey products\, a holomorphic analogue of ordinary triple Massey products for complex manifolds. Then\, I will discuss the (non)vanishing of these operations in situations of geometric interest\, including toric\, compact homogeneous Kähler\, and Calabi Yau manifolds.

SUMMARY:From p-adic Hodge theory to motivic cohomology and back
DESCRIPTION:Tess Bouis (Universität Regensburg) \nAbstract: The initial goal of p-adic Hodge theory\, as formulated by the foundational conjectures of Fontaine in the 1980s\, is to compare the different p-adic cohomology theories one can associate to schemes of mixed characteristic (0\,p). If Fontaine’s conjectures have now been solved by the work of many people\, the recent development of prismatic cohomology has shed new light on integral aspects of this theory. In this talk\, I want to explain how one can use these recent advances in p-adic Hodge theory to construct a new theory of motivic cohomology for general (qcqs) schemes. This theory generalises the recent construction of Elmanto-Morrow over a field to mixed characteristic\, and allows us to give a simplified motivic approach to certain classical results in p-adic Hodge theory. This is part of a joint work in progress with Arnab Kundu.

SUMMARY:Seminar on Arithmetic Geometry
DESCRIPTION:Zhixiang Wu (Universität Münster): Bernstein-Zelevinsky duality for locally analytic principal series representations \nBernstein-Zelevinsky duality is classically a duality on the derived category of smooth representations of a p-adic Lie group. In this talk\, we will consider the Bernstein-Zelevinsky duality for locally analytic representations of p-adic Lie groups\, and compute explicitly the duality for principal series representations. I will also explain the relationship of this duality with the duality of coherent sheaves on the (patched) eigenvariety.

SUMMARY:Seminar on Arithmetic Geometry
DESCRIPTION:Christian Dahlhausen  (Universität Heidelberg): Duality in (perfect) motivic homotopy theory \nThis talk treats a conjectured duality on modules over\nK-theory in the stable homotopy category of a scheme whose dualising\nobject is given by G-theory. I shall explain a proof of the conjecture\nfor quasi-excellent schemes in characteristic zero. In order to approach\nthe conjecture in positive characteristic\, I sketch the construction of\na “perfect motivic homotopy category” and compare it to the classical\nhomotopy category. For this perfect category\, I shall sketch the proof\nof an analogous version of the duality conjecture. This is joint work\nwith Denis-Charles Cisinski\, Jeroen Hekking\, and Storm Wolters. \nZoom (635 7328 0984\, Kenncode: kleinste sechsstellige Primzahl

SUMMARY:The Shintani–Faddeev modular cocycle: Stark units from q-Pochhammer ratios
DESCRIPTION:International Seminar on Automorphic Forms \nZhiyuan Li (SCMS\, Fudan University) \nThe Shintani–Faddeev modular cocycle: Stark units from q-Pochhammer ratios \nWe give a new interpretation of Stark units associated to real quadratic fields as special “real multiplication values” of a modular cocycle described by complex meromorphic continuation of a simple infinite product. The cocycle encodes the modular transformations of the infinite q-Pochhammer symbol and is related to the Shintani–Barnes double sine funciton and the Faddeev quantum dilogarithm. As a corollary\, we describe some intriguing features of the asymptotic behavior of the infinite q-Pochhammer symbol as the modular parameter approaches a real quadratic number. \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits)
