SUMMARY:Holomorphic triple products
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. This is joint work with Matthias Strauch. \nZoom (635 7328 0984\, Kenncode: kleinste sechsstellige Primzahl
