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 parameters of Hecke algebras for -adic groups
Kazuma Ohara
Let be a non-archimedean local field with residue characteristic and be a connected reductive group defined over . In earlier joint works with Jeffrey D. Adler, Jess…

Jeffrey D. Adler, Jessica Fintzen, Manish Mishra +1
Let be a nonarchimedean local field of residual characteristic . Let denote a connected reductive group over that splits over a tamely ramified extension of . Let…
Structure of Hecke algebras arising from types
Jeffrey D. Adler, Jessica Fintzen, Manish Mishra +1
Let denote a connected reductive group over a nonarchimedean local field of residue characteristic , and let denote an algebraically closed field of charac…
