Base change and the Mackey formula in Deligne--Lusztig theory
Sean Cotner
Using ideas of Digne and recent work of Gaitsgory--Rozenblyum--Varshavsky, we show that Lusztig induction commutes with (a minor variant of) the Glauberman correspondence for large…
Modular functoriality for finite groups
Sean Cotner
We develop an extension of Deligne--Lusztig theory to certain (possibly infinite type) disconnected reductive groups arising from the special fibers of point stabilizers in the Bru…
Local Langlands functoriality for Yu's supercuspidals II: Fargues--Scholze's parametrization
Sean Cotner, Tony Feng
This is the second of two papers dedicated to the explicit computation of the Fargues--Scholze correspondence. We compute the Tate cohomology of cuspidal representations arising fr…
Local Langlands functoriality for Yu's supercuspidals I: Kaletha's parametrization
Sean Cotner, Tony Feng
This is the first of two papers dedicated to the explicit computation of the Fargues--Scholze correspondence. In this first part, we construct (inspired by, and extending, Kaletha'…
Central isogenies and conjugacy classes in reductive groups
Sean Cotner
Steinberg described the group of components of the centralizer of a semisimple element of a connected semisimple algebraic group as a subgroup of the fundamental group of .…
