On the finiteness of the second moment of the number of critical points of Gaussian random fields
Abstract
We prove that the second moment of the number of critical points of any sufficiently regular random field, for example with almost surely C3 sample paths, defined over a compact Whitney stratified manifold is finite. Our results hold without the assumption of stationarity - which has traditionally been assumed in other work. Under stationarity we demonstrate that our imposed conditions imply the generalized Geman condition of Estrade 2016.
