复解析簇上的类似向量场

Gradient-like vector fields on a complex analytic variety

Cheol-Hyun Cho, Giovanni Marelli

摘要:

给定复维数n的Whitney分层复解析簇上的复解析函数f,其实部Re(f)为Morse,我们证明了Re(f)的分层类梯度向量场的存在性,使得复维数s的层S上临界点p的不稳定集具有Goresky和MacPherson所证明的实维数$m(p)+n-s$.

英文摘要:

Given a complex analytic function f on a Whitney stratified complex analytic variety of complex dimension n, whose real part Re(f) is Morse, we prove the existence of a stratified gradient-like vector field for Re(f) such that the unstable set of a critical point p on a stratum S of complex dimension s has real dimension $m(p)+n-s$ as was conjectured by Goresky and MacPherson.
