A central limit theorem for Lipschitz-Killing curvatures of Gaussian excursions

This paper studies the excursion set of a real stationary isotropic Gaussian random field above a fixed level. We show that the standardized Lipschitz-Killing curvatures of the intersection of the excursion set with a window converges in distribution to a normal distribution as the window grows to the d-dimensional Euclidean space. Moreover a lower bound for the asymptotic variance is derived. (C) 2017 Elsevier Inc. All rights reserved.
