| Abstract: | Kress transformation,the integral method processing the first class singular kernel and single-layer potential mainly adopted to solve the exterior Dirichlet problem in sharp corner area.Examples of specific algorithms and numerical are given in this article,through which it can be seen that using the single layer potential to solve the exterior Dirichlet problem in sharp corner area has the same results as with combination of single and double layer,indicating that this method is effective and feasible. |
