Abstract
The Iwasawa algebra of a compact p-adic Lie group is fundamental to the study of the representations of the group. Understanding this representation theory is crucial in progress towards a (mod p)local Langlands correspondence. However, much remains unknown about Iwasawa algebras and their modules.
In this talk we’ll aim to measure the size of the Iwasawa algebra and its representations. I’ll explain the algebraic tools we use to do this – Krull dimension and canonical dimension – and survey previously known examples. Our main result is a new bound on these dimensions for the group SL_2(O_F), where F is a finite extension of the p-adic numbers. When F is a quadratic extension, we find the Krull dimension is exactly 5, as predicted by a conjecture of Ardakov and Brown.
Series This talk is part of the Junior Algebra and Number Theory seminar series.
