摘  要：Deligne--Lusztig varieties are fundamental objects in the study of irreducible representations in characteristic 0 of finite reductive groups. In this talk, I will discuss the cohomology of the structure and canonical sheaf for compactified Deligne--Lusztig varieties, as one of the first steps in understanding the situation in defining characteristic.
