Luca Marannino: Anticyclotomic Iwasawa theory of modular forms at inert primes via diagonal classes

Abstract: In this talk, we outline an approach to the study of anticyclotomic Iwasawa theory of modular forms when the fixed prime p is inert in the relevant quadratic imaginary field. Following ideas of Castella-Do for the “p split” case, one can envisage a construction of an anticyclotomic Euler system arising from a suitable manipulation of certain Galois cohomology classes known as diagonal classes. We will report on this work in progress, trying to underline the main difficulties arising in the “p inert” setting.

Alexander Ivanov: Meromorphic vector bundles on the Fargues-Fontaine curve

Abstract: Recently, two different constructions of a geometric local Langlands category were given: the analytic construction of Fargues—Scholze and the schematic one of Hemo—Zhu (in progress). Motivated by the goal of finding a relation between these, we construct the stack of meromorphic vector bundles, which interpolates between the geometric objects on analytic and schematic sides. We sketch some of its geometric properties, e.g. how the Fargues—Scholze charts M_b naturally appear in it. This is joint work with Ian Gleason and Felix Zillinger.
