Random walks inside a domain for estimation of the gradient of solutions to elliptic boundary value problems
Published/Copyright:
January 27, 2008
Elliptic boundary value problems for the Helmholtz equation are considered in the paper. In order to estimate their solutions and also the gradient of the solution, a special probabilistic representation and a corresponding statistical algorithm are constructed. The algorithm is a version of the process of ‘walking over spheres and in balls’ for solving a system of local integral equations obtained from the original differential problem by using the central and noncentral Green functions for the Helmholtz operator in a ball.
