We study singular hyperkähler quotients of the cotangent bundle of a complex semisimple Lie group as stratified spaces whose strata are hyperkähler. We focus on one particular case where the stratification satisfies the frontier condition and the partial order on the set of strata can be described explicitly by Lie theoretic data.

半简单李代数的分层HyperKähler空间

我们将复杂的半简单Lie群的余切束的奇异hyperkähler商研究为分层为hyperkähler的分层空间。我们关注的是一种特殊情况,其中分层满足边界条件,并且可以通过李理论数据明确描述层集上的部分顺序。
