    Abstract

    Given any Morse function $f$ on a Whitney stratified complex analytic variety
    of complex dimension $n$, we prove the existence of a stratified gradient-like
    vector field for $f$ 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.
