Title:

Deep level Deligne-Lusztig varieties in the tamely ramified case

Abstract:

Deep level Deligne-Lusztig varieties are natural analogues of classical Deligne-Lusztig varieties, and have interesting applications in the study of supersuspical representations of p-adic groups. I will discuss work in progress on the construction of deep level Deligne-Lusztig varieties for tamely ramified reductive groups, which are expect to extend previous work in the unramified case. Joint work with A. Ivanov.
