Almost multiplicity-one property of spherical varieties over finite fields

Fulin Chen, Fang Shi, Shaobin Tan

Let $H$ be a connected algebraic subgroup of a connected reductive group $G$ over a finite field $F_{q}$ such that $G / H$ is a $G$ -spherical variety, i.e., $G / H$ has an open d…

Local Weyl modules and skew Howe duality

Fulin Chen, Xin Huang, Siyi Niu +1

The skew $(gl_{n}, gl_{r})$ Howe duality states that the exterior algebra $I^ (C^{n r})$ admits a multiplicity-free decomposition under the natural act…

Non-weight modules over gap- $p$ Virasoro algebras

Chengkang Xu, Fulin Chen, Shaobin Tan

In this paper, we study non-weight modules over gap- $p$ Virasoro algebras, including Whittaker modules, $U (C L_{0})$ -free modules and their tensor products. We est…
