Ryosuke Sato

I am a postdoctoral fellow at Department of Physics, Faculty of Science and Engineering, Chuo University.
(email: r.sato@phys.chuo-u.ac.jp )
My research interests encompass Operator Algebra Theory and Probability Theory. Specifically, I focus on Asymptotic Representation Theory, which study representations of inductive limits of compact groups, and its extension to Quantum Groups. From the perspective of Operator Algebra Theory, this area intersects with the Representation Theory of AF (approximately finite-dimensional) algebras, while Probability Theory plays a significant role in this field. Additionally, I am intrigued by Probability Theory with algebraic origins, such as stochastic processes and point processes, which emerge within the framework of Representation Theory.
