A connection between minimal nilpotent orbits of types A and D via Hamiltonian reduction

Baohua Fu, Jie Liu

We establish a novel connection between the minimal nilpotent orbit $O_{n}$ in $sl_{n}$ and the minimal nilpotent orbit closure $O_{n}$ in $\mathf…

Hamiltonian reductions as affine closures of cotangent bundles

Baohua Fu, Jie Liu

Let $Y$ be an irreducible non-singular affine $G$ -variety with a $2$ -large action. We show that the Hamiltonian reduction $T^{*} Y / / / G$ is a symplectic variety with terminal s…
