| Outline of Final Research Achievements |
We researched new developments of theory of generalized functionals, an infinite dimensional stochastic analysis based on the theory,and its applications.We obtained remarkable results:①We constructed spaces of generalized functionals from new spaces consisting of distributions that are closed in the product of distributions,and also obtained an integral expressions of the higher order Levy Laplacians.Moreover,we obtained a SDE including random directional differentiations induced from the delta distribution centered at powers of an infinite dimensional Brownian motion.②We initiated the new method of stochastic integral for instantly independent stochastic processes,and proved the Doob-Meyer type decomposition theorem. ③We proved that the nuclearity of the space of test functionals for infinite dimensional distributions is a necessary and sufficient condition for a characterization of the S-transform.The result is the breakthrough as an answer for an unsolved problem.
