| Outline of Final Research Achievements |
Mathematical models in partial differential equations with singularities have been used frequently in studies of natural phenomena and social phenomena. They are important research themes for the development of every fields in engineering and financial engineering and so on. In this research project, the representative proposed a higher-order finite difference scheme for nonlinear two-point bpundary value problems. The representative also made progresses in the study of numerical solutions of initial-boundary value problems of parabolic equations on two dimensional spatial domains. Results of numerical analysis of the higher order are obtained.
