Abstract:
Let X be a centered Gaussian random vector taking values in a separable Hilbert space H, and let a∈H. We investigate the behavior of the density and the distribution function of a noncentered ball ‖X−a‖2 by means of its Laplace transform and obtain the results with an optimal estimate of the accuracy rate. As a tool we use a “local limit theorems” approach.
Keywords:
small balls, Gaussian measure, Hilbert space, Laplace transform.
