Education and career
Matsumoto graduated from the University of Tokyo in 1981.[1] He got a doctoral degree from Rikkyo University in 1986,[1] advised by Akio Fujii.[2] His thesis was titled Discrepancy estimates for the value-distribution of the Riemann zeta-function.[2] He became a lecturer at Iwate University in 1987 and an associate professor there in 1990.[1] He joined Nagoya University in 1995, becoming a full professor there in 2001.[1]
Research
Matsumoto's specializations include number theory, zeta theory, and mathematical analysis. He is mostly recognized for the Matsumoto zeta function, a zeta function named after him. He co-edited Analytic Number Theory (2002), a book about prime numbers, divisor problems, Diophantine equations, and other topics related to analytic number theory, including Diophantine approximations, and the theory of zeta and L-functions.[3] His other book, Algebraic And Analytic Aspects Of Zeta Functions And L-Functions, a compilation of lectures at the French-Japanese Winter School, was published in 2010.[4]
