Popis: Let X = {X(t) ∈ ℝd,t ∈ ℝN} be a centered space-time anisotropic Gaussian random field whose components are independent and satisfy some mild conditions. We study the packing dimension of range X(E) under the anisotropic (time variable) metric space (ℝN,ρ) and (space variable) metric space (ℝd, τ), where E ⊂ ℝN is a Borel set. Our results generalize the corresponding results of Estrade, Wu and Xiao (Commun. Stoch. Anal., 5, 41–64 (2011)) for time-anisotropic Gaussian random fields to space-time anisotropic Gaussian fields.
