Canonical Bernstein-Zelevinsky Filtration and Casselman's Comparison Conjecture

Kaidi Wu, Jun Yu

We establish a canonical Bernstein--Zelevinsky filtration for Casselman--Wallach representations that is analogous to the $p$ -adic case. In addition, we outline an approach to Cass…

Radical subgroups of finite reductive groups

Zhicheng Feng, Jun Yu, Jiping Zhang

Radical subgroups play an important role in both finite group theory and representation theory. This is the first of a series of papers of ours in classifying radical $p$ -subgroups…

Cartan--Helgason theorem for quaternionic symmetric and twistor spaces

Clemens Weiske, Jun Yu, Genkai Zhang

Let $(g, k)$ be a complex quaternionic symmetric pair with $k$ having an ideal $sl (2, C)$ , $\mathfrak{k}=\mathfrak{sl}(2, \math…

A proof of Casselman's comparison theorem for standard minimal parabolic subalgebra

Ning Li, Gang Liu, Jun Yu

Let $G$ be a real linear reductive group and $K$ be a maximal compact subgroup. Let $P$ be a minimal parabolic subgroup of $G$ with complexified Lie algebra $p$ , and $\m…
