| Outline of Final Research Achievements |
Differential equations and integral equations with singularities often arise in physics and chemistry, but numerical simulation of those equations is difficult by means of existing general numerical methods. For such equations, existing methods cannot achieve their usual performance, and there is no theoretical support of convergence to the solution. This study developed a highly efficient numerical method based on the Sinc numerical methods, which are robust and efficient for singularities. This study also gave theoretical support of the proposed method.
