上齐性单流形上的GKM作用

GKM actions on cohomogeneity one manifolds

Oliver Goertsches, Eugenia Loiudice, Giovanni Russo

摘要:

考虑紧致流形$M$,其上齐性为紧致李群$G$的一个作用,使得轨道空间$M/G$是一个闭区间.对于$T$是$G$的极大环面,我们在$M$的群图上找到了使$M$上的$T$ -作用是GKM型的充要条件,并描述了它的GKM图.显式的例子说明的一般结果。

英文摘要:

We consider compact manifolds $M$ with a cohomogeneity one action of a compact Lie group $G$ such that the orbit space $M/G$ is a closed interval. For $T$ a maximal torus of $G$, we find necessary and sufficient conditions on the group diagram of $M$ such that the $T$-action on $M$ is of GKM type, and describe its GKM graph. The general results are illustrated on explicit examples.
