History

Many outstanding mathematical research have been conducted at the department of mathematics since its foundation in 1930. Cutting-edge research results have been produced continually including Kiyoshi Oka, who did fundamental work in the theory of several complex variables, Zenjiro Kuramochi, who is famous for the theory of Kuramochi boundary, and Noboru Tanaka, who is famous for the theory of Tanaka-connection in CR geometry.
