Abstract

We consider a class of gradient-like flows on three-dimensional closed manifolds whose attractors and repellers belongs to a finite union of embedded surfaces and find conditions when the ambient manifold is Seifert.

关于 Seifert 流形上的梯度流

摘要

我们在三维封闭流形上考虑一类梯度流，其吸引子和排斥器属于嵌入表面的有限联合，并找到当环境流形为 Seifert 时的条件。
