| Research Abstract |
Since partial differential equations (PDE) are used to in mathematical modeling of various natural phenomena, the development of numerical methods and their numerical analysis for PDE is an important subject not only in the theory of PDE but also in the practical fields of physics, chemistry, biology, engineering, financial marketing, and so on. In this research project, the representative made progresses in the study of one-dimensional two-point boundary value problems and two-dimensional elliptic boundary value problems. Higher order numerical methods are proposed and numerical analysis of them is carried out.
