A depth-zero principal-series block whose Hecke algebra has a non-trivial two-cocycle

Jeffrey D. Adler, Jessica Fintzen, Kazuma Ohara

Recently the authors have shown that every Hecke algebra associated to a type constructed by Kim and Yu is isomorphic to a Hecke algebra for a depth-zero type. An example in the li…

On smooth-group actions on reductive groups and spherical buildings

Jeffrey D. Adler, Joshua M. Lansky, Loren Spice

Let $k$ be a field, and suppose that $Γ$ is a smooth $k$ -group that acts on a connected, reductive $k$ -group $G$ . Let $G$ denote the maximal smooth, connected subgroup o…
