معرفی
Reiji Tomatsu is a Professor at Hokkaido University’s Faculty of Education and Integrated Arts and Sciences, specializing in Operator Algebras and Quantum Groups. His research focuses on the structural analysis of von Neumann algebras and their interactions with quantum symmetries.
- Education: PhD in Mathematical Sciences from the University of Tokyo.
Research Interests revolve around quantum group actions, Rohlin flows, Haagerup approximation properties, and classification of operator algebras. He investigates infinite tensor product actions, coideals, and modular invariants, often leveraging functional analysis and mathematical physics frameworks.
His recent publications emphasize quantum group dynamics and von Neumann algebra structures, including classification theorems for coideal $C^*$-algebras and fullness of type III factors. These works intersect with noncommutative geometry and representation theory.
Grants: He has continuously received Japan Society for the Promotion of Science (JSPS) research grants since 2007, advancing studies on quantum group actions and operator algebraic symmetries.
Teaching: Tomatsu delivers graduate-level courses in analysis, Fourier analysis, and mathematics education at Hokkaido University’s Graduate School of Education.
