Outline Activities
I have been studying and teaching Stochastic Analysis, especially Stochastic Complex Analysis. Just after Feynman
developed his famous path integral, M. Kac pointed out that the Wiener integral is the counter part to it. In particular, a stochastic oscillatory integral is the one to Feynman path integral representation of propergator. The asymptotic behavior of stochastic oscillatory integral relates to the semi-classical limits. I introduced a new complixification of the path space and established complex change of variables formulae. With these, I am studying the principle of tationary phase on the path space. I am also invetigating the KdV equations via stochatic oscillatory integrals. Moreover, I recently obtained a diffusion process on a sub-Riemannian manifold by rolling the manifold, and have been investigating the properties of the process and its applications to sub-laplacian analysis.
I have been teaching to graduate students about stochastic models appearing in Mathematical Finance. Moreover, in the joint work with the Nisshin Fire & Marine Insurance Co., I investigated stochastic models in the non-life insurance during AY2008-2012.

| 1. | Hiroyuki Matumoto, Setsuo Taniguchi, Stochastic Analysis -- Itô and Malliavin Calculus in Tandem, Cambridge Univ. Press, https://doi.org/10.1017/9781316492888, 2017.01, [URL], Thanks to the driving forces of the Itô calculus and the Malliavin calculus, stochastic analysis has expanded into numerous fields including partial differential equations, physics, and mathematical finance. This book is a compact, graduate-level text that develops the two calculi in tandem, laying out a balanced toolbox for researchers and students in mathematics and mathematical finance. The book explores foundations and applications of the two calculi, including stochastic integrals and differential equations, and the distribution theory on Wiener space developed by the Japanese school of probability. Uniquely, the book then delves into the possibilities that arise by using the two flavors of calculus together. Taking a distinctive, path-space-oriented approach, this book crystallizes modern day stochastic analysis into a single volume.. |
