| Outline of Final Research Achievements |
This study is concerned with rigorous convergence of meshfree collocation methods for nonlinear parabolic equations and linear stochastic partial differential equations, as well as with finding useful classes of basis functions and grid structures. For those equations defined on whole space, the study clarified the classes of basis functions and grid structures for which the corresponding approximation methods rigorously converge to the original equations. Also, these convergences are confined by numerical experiments. These results show that for finite horizon stochastic control problems and filtering problems for diffusion processes, the study reveals numerical methods that guarantee the rigorous convergences and need less computational time as compared with existing methods.
