Abstract

Let (M,g)(M,g) be a closed Riemannian manifold, and let F:MRF:M \to \mathbb{R} be a smooth function on MM. We show the following holds generically for the function FF: for each maximum pp of FF, there exist two minima, denoted by m+(p)m_+(p) and m(p)m_-(p), so that the gradient flow initialized at a random point close to pp converges to either m(p)m_-(p) or m+(p)m_+(p) with high probability. The statement also holds for FC(M)F \in C^\infty(M) fixed and a generic metric gg on MM. We conclude by associating to a given a generic pair (F,g)(F, g) what we call its max-min graph, which captures the relation between minima and maxima derived in the main result.
