Spherical actions on isotropic flag varieties and related branching rules

Roman Avdeev, Alexey Petukhov

Let $G$ be a symplectic or special orthogonal group, let $H$ be a connected reductive subgroup of $G$ , and let $X$ be a flag variety of $G$ . We classify all triples $(G, H, X)$ such…

Primitive ideals of $U (sl (\infty))$ and the Robinson-Schensted algorithm at infinity

Ivan Penkov, Alexey Petukhov

We present an algorithm which computes the annihilator in $U (sl (\infty))$ of any simple highest weight $sl (\infty)$ -module $L_{b} (λ)$ . This algorithm is bas…
