A conjectural construction of Arthur Packets in Fargues-Scholze's categorical local Langlands correspondence
Kam Fai Tam 氏 (Xiamen Malaysia University)
A conjectural construction of Arthur Packets in Fargues-Scholze's categorical local Langlands correspondence
[ 講演概要 ]
The presentation consists of two parts. In the first part, we review -- from a novice point of view -- the categorical local Langlands correspondence due to Fargues and Scholze. Topics include: the structure of Bun_G and LocSys_{\hat G}, spectral action via Hecke operators, geometric Satake transform, and some conjectural consequences proposed by Fargues. (Apologies: the p-adic geometry underlying the relative Fargues-Fontaine curve is not included.)
In the second part, I will present a conjectural construction of Arthur packets in Fargues-Scholze's framework. This construction is based on the vanishing cycle functor introduced by Cunningham-Fiori-Moussaoui-Mracek-Xu, which is in turn inspired by Adams-Barbasch-Vogan for real groups. (A confession for curious audiences: this presentation offers essentially no new results. My goal is to illustrate how the legacy of James Arthur may influence other theories.)
