| Research Abstract |
Ito studied applications of renormalization group method in mathematical sciences from various points of view. He investigates the Ricci flows from statistical mechanics point of view, and suggested that the transformation of manifolds by the flow is strongly related to the Pirogov-Sinai theory of phase transitions.
He also reconsidered the paper by Ya Sinai and D.Li on the constructions of (complex) turbulent solution of Navier-Stokes equation of fluid, using the renormalization group type argument. It seems that the paper needed some calculations to be understood. Ito studied quark confinement problem some decades ago, and established confinement in the hierarchical approximation of the Migdal-Kadanov type. However there appeared a misleading paper in which the author claimed that he established the confinement.
Ito and Prof.E.Seiler of MaxPlanck Institute argued how and why he made mistakes in his arguments.
