Shinzo Watanabe

Shinzō Watanabe (渡辺 信三 Watanabe Shinzō, 23 December 1935) is a Japanese mathematician, who works on probability theory, stochastic processes and stochastic differential equations.

Watanabe received from Kyoto University in 1958 his bachelor's degree and in 1963 his Ph.D. under Kiyosi Itô. Watanabe became a professor at Kyoto University. He was also a visiting professor at Stanford University and participated in the organizing committees of international Japanese/Soviet seminars on probability theory.

In 1989 he received the Autumn Prize of the Mathematical Society of Japan. In 1983 he was an invited speaker at the International Congress of Mathematicians in Warsaw (Excursion point processes and diffusion).
