Deligne–Lusztig theory is a significant area in the field of representation theory of algebraic groups and finite groups of Lie type, named after Pierre Deligne and George Lusztig. This theory provides a way to construct and study representations of finite groups of Lie type via geometric methods, specifically by examining varieties over finite fields.
