摘要
In this work we propose using the method of fundamental solutions (MFS) to solve boundary value problems for the Helmholtz-Beltrami equation on a sphere. We prove density and convergence results that justify the proposed MFS approximation. Several numerical examples are considered to illustrate the good performance of the method.
