设M是一个具有真矩映射的哈密顿T空间,在某个分支下有界。在此背景下,我们给出了M的T-等变上同调的一个组合刻画,推广了Goresky,Kottwitz和MacPherson的结果以及Tolman和Weitsman的技巧。此外,当M具有与T的作用反交换的反辛对合σ时,我们也将这些结果的“mod2”形式推广到M的实轨迹Q:=M。我们给出了这些结果在超曲面变种理论中的应用。
Let M be a Hamiltonian T space with a proper moment map, bounded below in some component. In this setting, we give a combinatorial description of the T -equivariant cohomology of M, extending results of Goresky, Kottwitz and MacPherson and techniques of Tolman and Weitsman. Moreover, when M is equipped with an antisymplectic involution σ anticommuting with the action of T , we also extend to this noncompact setting the “mod 2” versions of these results to the real locus Q := M of M. We give applications of these results to the theory of hypertoric varieties.
