摘要：In this talk I would start by introducing classical DeligneLusztig theory via concrete examples. Then I discuss its generalisation for reductive groups over discrete valuation rings. In this latter case, besides the DeligneLusztig theory one also has a clifford theoretic approach to their representations, using orbits of the Lie algebras; I will report some recent progress concerning the interaction between higher DeligneLusztig representations and these orbits.
