Numerical solutions of stationary diffusion equations on the unit sphere with isotropic lognormal diffusion coefficients are considered. Hölder regularity in $$L^p$$ Lp sense for isotropic Gaussian random fields is obtained and related to the regularity of the driving lognormal coefficients. This yields regularity in $$L^p$$ Lp sense of the solution to the diffusion problem in Sobolev spaces. Convergence...
We describe the analysis and the implementation of two finite element (FE) algorithms for the deterministic numerical solution of elliptic boundary value problems with stochastic coefficients.They are based on separation of deterministic and stochastic parts of the input data by a Karhunen–Loève expansion, truncated after M terms. With a change of measure we convert the problem to a sequence of M-dimensional,...
