拓扑流形上的等变路场

Equivariant path fields on topological manifolds

Lucilia Borsari, Fernanda Cardona, Peter Wong

摘要:

H. Hopf断言一个闭连通光滑流形允许无处消失的向量场当且仅当它的欧拉示性数为零。R.布朗将霍普夫的结果推广到拓扑流形,用路径场代替向量场。本文对局部光滑$G$ -流形给出了Brown定理的一个等变类比,其中$G$是有限群.

英文摘要:

A classical theorem of H. Hopf asserts that a closed connected smooth manifold admits a nowhere vanishing vector field if and only if its Euler characteristic is zero. R. Brown generalized Hopf's result to topological manifolds, replacing vector fields with path fields. In this note, we give an equivariant analog of Brown's theorem for locally smooth $G$-manifolds where $G$ is a finite group.
