 4d-ee50-4086-aed1-ae4c0099ca10%22Abstract: The goal of the seminar is to e
 xplain parts of the joint work https://arxiv.org/abs/2010.01906. In his re
 markable work Vincent Lafforgue constructed a decomposition of the space o
 f (cuspidal) automorphic forms parameterized by semi-simple Langlands para
 meters for the Langlands dual group. The goal of the seminar will be to ex
 plain a ``categorification'' of Lafforgue's result\, from which the  (unra
 mified case of) of Lafforgue's result follows. Namely\, our first goal wil
 l be to introduce a new algebro-geometric object - the (derived) stack Loc
 Sys of local systems and to describe its properties.  Our second goal will
  be to construct an action of ``the symmetric monoidal category of quasi-c
 oherent sheaves on LocSys for the Langlands dual group'' on ``the category
  of sheaves on the moduli space of G-bundles with nilpotent singular suppo
 rt''\, also called the spectral action. Our third goal will be to explain 
 how to deduce the unramified case of the original Lafforgue's result by th
 e so-called ``trace of Frobenius' construction. Prerequisites: The seminar
  will be about algebraic geometry and category theory rather than represen
 tation theory.  In particular\, while no particular background in Langland
 s program or representation theory is needed\, a familiarity with (stable)
  infinity categories\, derived categories\, t-structures\, symmetric monoi
 dal categories and algebraic stacks will be helpful. \n\nAdd to CalendarOu

DESCRIPTION:Date: \n\nTue\, 28/06/202212:00-13:00\n\n\nSee also: Topology &
  Geometry\, Seminars\, Events & Seminars\n\n\nI will give an overview of t
 he theory of Categorical Enumerative Invariants (CEIs)\, as developed in j
 oint work with Junwu Tu and Kevin Costello. The emphasis will be on the ro
 le played by the Givental group\, which controls the effect of changes of 
 splitting on the CEIs. \nIf time allows I will state two new conjectures w
 hich relate the derived category of the nodal cubic with the classical $\l
 ambda_g$ conjecture in Gromov-Witten theory\, due to Getzler\, Faber and P
 andharipande. The new work is joint with Weng-Him Cheung and Yunfan He\, a
 nd builds on work of Yefeng Shen and Junwu Tu (unpublished).\n\nAdd to Cal
