摘要
设 为 上的简单经典李代数, 为伴随群。考虑幂零元 及伴随轨道 。由于 Kraft 与 Procesi 的工作,闭包 中余维数 轨道的形式切片已为人所知。在本文中,我们对 的万有 -等变覆盖 证明了类似结果。即,我们描述了其仿射化 的余维数 奇点。

I am grateful to Shilin Yu for pointing out a mistake in the first version of the paper. The second version includes description of symmetries acting on the codimension 2 singularities, and a discussion of expected symplectic duality, which this paper provides evidence to
