$K$ -type multiplicities in degenerate principal series via Howe duality

Mark Colarusso, William Q. Erickson, Andrew Frohmader +1

Let $K$ be one of the complex classical groups $O_{k}$ , $GL_{k}$ , or $Sp_{2 k}$ . Let $M \subseteq K$ be the block diagonal embedding ${\rm O}_{k_1} \times \cdots \time…

Orbits on a product of two flags and a line and the Bruhat Order, I

Mark Colarusso, Sam Evens

Let $G = G L (n)$ be the $n \times n$ complex general linear group and let $B_{n}$ be its flag variety. The standard Borel subgroup $B$ of upper triangular matrices acts on th…
