Wave equation with a coloured stable noise

Probability 2017-07-27 v1

Abstract

We define a random measure generated by a real anisotropic harmonizable fractional stable field ZHZ^H with stability parameter α(1,2)\alpha\in(1,2) and Hurst index H(1/2,1)H\in(1/2,1) and prove that the measure is σ\sigma-additive in probability. An integral with respect to this measure is constructed, which enables us to consider a wave equation in R3\mathbb R^3 with a random source generated by ZHZ^H. We show that the solution to this equation, given by Kirchhoff's formula, has a modification, which is H\"older continuous of any order up to (3H1)1(3H-1)\wedge 1. In the case where H(2/3,1)H\in(2/3,1), we show further that the modification is absolutely continuous.
