Outline of Final Research Achievements |
We study existence and uniqueness of infinite dimensional stochastic differential equations (ISDEs). We clarified the relation between the uniqueness of solutions and the triviality of tail sigma fields. Applying the result, we obtained the uniqueness of strong solutions of ISDEs describing the systems of Brownian motions with long range interaction including logarithmic potential, and determined the Dirichlet forms associated with the systems.
