A professor at Department of Mathematics at Hiroshima University. He considers himself as a mathematician, but is not confident. There are so many Makoto Matsumoto's in Japan (quite a common name). The famous senior mathematician Makoto Matsumoto, who majors Finsler geometry, is another person, but in MathReview there is a confusion. Sorry.


Every Mathematics; in particular algebraic researches. Weak side is analysis. Arithmetic fundamental groups, mapping class groups, combinatorics, pseudorandom number generation, computer science, etc. are his research areas.

A dream

To be a mathematician. But it seems hard.
