Abstract

A new mesh-free stochastic spectral method based on a spectral inversion of the Poisson integral formula is suggested. We consider the cases of Laplace equation and the system of elasticity equations for domains consisting of overlapping discs, half-planes, spheres, and half-spaces. A randomized projection method we developed in Sabelfeld and Loshchina (2010) [21] is used to solve the system of linear equations approximating the integral equations whose phase space is the intersection surfaces of the domains.
