Fourier Transform and Gaussian Random Fields Brief summary of the Fourier transform and how to generate stationary Gaussian random fields in one and two dimensions. WebIn this talk, we study the local times of anisotropic Gaussian random fields satisfying strong local nondeterminism with respect to an anisotropic metric. By applying moment estimates for local times, we prove optimal local and global Hölder conditions for the local times for these Gaussian random fields and deduce related sample path properties. black dining table with red chairs https://florentinta.com
