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.

Deep image prior for inverse problems: acceleration and probabilistic treatment
AbstractSince its first proposal in 2018, deep image prior has emerged as a very powerful unsupervised deep learning technique for solving inverse problems. The approach has demonstrated very encouraging empirical success in image denoising, deblurring, super-resolution etc. However, there are also several known drawbacks of the approach, notably high computational expense. In this talk, we des...
