Theory of Operator Algebras I. Since its inception by von Neumann 70 years ago, the theory of operator algebras has become a rapidly developing area of importance for the understanding of many areas of mathematics and theoretical physics. Accessible to the non-specialist, this first part of a three volume treatise provides a clear, Author: M. Takesaki. In the theory of von Neumann algebras, a part of the mathematical field of functional analysis, 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. The operator h′ = h−1 in Theorem is called the Radon–Nikodym derivative of φ with respect to ωand often denoted by dφ/dω, due to the following result, which, if the algebra M is abelian, is the well-known Radon–Nikodym Theorem from measure bgbeach.info by: Additional topics, for example, Tomita Takasaki theory, subfactors, group actions, and noncommutative probability.

I am sorry, that I interfere, but you could not paint little bit more in detail.

Also that we would do without your very good idea

As that interestingly sounds
