We calculate the integral equivariant cohomology, in terms of generators and relations, of locally standard torus orbifolds whose odd degree ordinary cohomology vanishes. We begin by studying GKM-orbifolds, which are more general, before specializing to half-dimensional torus actions.

圆环的等变上同调

我们根据生成元和关系计算其奇次普通上同调消失的局部标准环环的积分等变上同调。我们首先研究更一般的 GKM-orbifolds，然后专门研究半维环面动作。
