| 总结: | This research is to compute the Green’s function on an unbounded simply connected region by conformal mapping and by solving an exterior Dirichlet problem. The exact Green’s function is found by using Riemann mapping and M bius transform. The Dirichlet problem is then solved using a uniquely solvable Fredholm integral equation on the boundary of the region. The kernel of this integral equation is the generalized Neumann kernel. The method for solving this integral equation is by using the Nystr?m method with the trapezoidal rule to discretize it into a system. The linear system is solved by the Gaussian elimination method. As an examination of the proposed method, several numerical examples for some various test regions are presented. These examples include a comparison between the numerical result and the exact solutions. |
