2 unusual facts about Deligne–Lusztig theory


Bhama Srinivasan

She has co-authored a number of papers with Paul Fong in modular representation theory and Deligne–Lusztig theory.

Green function

Deligne–Lusztig theory (Green function) in the representation theory of finite groups of Lie type.


Algebraic surface

This theorem is not only the tool for the research of surfaces but also used for the proof of the Weil conjecture by Deligne because it is true on the algebraically closed field.

Nagata's compactification theorem

Deligne showed, in unpublished notes expounded by Conrad, that the condition that S is Noetherian can be replaced by the condition that S is quasi-compact and quasi-separated.

Pierre Deligne

In joint work with George Lusztig, Deligne and Lusztig applied étale cohomology to construct representations of finite groups of Lie type; with Michael Rapoport, Deligne worked on the moduli spaces from the 'fine' arithmetic point of view, with application to modular forms.
