SUMMARY:Workshop / Seminar:Learning seminar in algebraic combinatorics: Torsion classes realize the Tamari lattice in type A
DESCRIPTION:The protagonist of this talk will be the oriented quiver of Dynkin type A. We will introduce its (finitely many) indecomposable representations\, use them to classify all quotient-closed subcategories of rep A_n\, and discover which among these constitute torsion classes via \"bracket vectors\". The torsion classes ordered by inclusion recover the Tamari lattice\, a beloved combinatorial lattice encoding a variety of known objects. This talk follows the paper \"The Tamari lattice as it arises in quiver representations\" by Hugh Thomas.

SUMMARY:Workshop / Seminar:Student Number Theory: The local Langlands correspondence for tori
DESCRIPTION:In this talk\, I will discuss the local Langlands correspondence for tori\, as detailed in Yu's paper \"On the local Langlands correspondence for tori.\" I will state and prove some special cases of the correspondence\, and then will state and prove it in full generality\, using techniques from class field theory.
