Next year marks the 50th anniversary of publication of Professor Masamichi Takesaki’s Springe Lecture Notes volume, “Tomita’s theory of modular Hilbert algebras and its applications.” Tomita–Takesaki theory is a method for constructing modular automorphisms of von Neumann algebras from the polar decomposition of a certain involution. It is essential for the theory of type III factors, and has led to a good structure theory for these previously intractable objects.

A conference will be held to celebrate this special occasion on June 15-19, 2020 at the University of Tokyo, Japan. The conference is open to the public.
