Projections of nilpotent orbits in a simple Lie algebra and shared orbits

Dmitri I. Panyushev

Let $G$ be a simple algebraic group with $g = L i e (G)$ and $O \subset g$ a nilpotent orbit. If $H$ is a reductive subgroup of $G$ with $L i e (H) = h$ ,…

Orbits and invariants for coisotropy representations

Dmitri I. Panyushev

For a subgroup $H$ of a reductive group $G$ , let $m \subset g^{*}$ be the cotangent space of $eH \in G / H$ . The linear action $(H : m)$ is the coisotropy rep…
