| Abstract: | Harmonic equation had extensive application in science and engineering.In this paper,based on the definition of Green function with basic solution,the integral expression of harmonic function in exterior of the bounded region was derived. On this basis,it gives the Green function of the exterior Dirichlet problem for harmonic equation and the conditions. Finally,by using this Green function,the solution is given in the exterior domain of a sphere,which is for the exterior Dirichlet problem of harmonic equat... |
