Contravariant forms on Whittaker modules

Adam Brown, Anna Romanov

Let $g$ be a complex semisimple Lie algebra. We give a classification of contravariant forms on the nondegenerate Whittaker $g$ -modules $Y (χ, η)$ introduced b…

Finite Gelfand pairs and cracking points of the symmetric groups

Faith Pearson, Anna Romanov, Dylan Soller

Let $Γ$ be a finite group. Consider the wreath product $G_{n} := Γ^{n} ⋊ S_{n}$ and the subgroup $K_{n} := Δ_{n} \times S_{n} \subseteq G_{n}$ , where $S_{n}$ is the symmetric group and $Δ_{n}$ …
