Let u be a unipotent element in the totally positive part of a complex reductive group. We consider the intersection of the Springer fibre at u with the totally positive part of the flag manifold. We show that this intersection has a natural cell decomposition which is part of the cell decomposition (Rietsch) of the totally positive flag manifold.

弹力纤维的总准度

假设您是一个复杂的还原族的整体正部分的单能元素。我们考虑u处的Springer纤维与旗形歧管的完全正部分的交点。我们证明此交点具有自然的细胞分解，这是完全正向标记流形的细胞分解（Rietsch）的一部分。
