CAMBRIDGE INDIA Modular Theory In Operator Algebras 2021 Edition by Serban Valentin Stratila,
The first edition of this book appeared in 1981 as a direct continuation of Lectures of von Neumann Algebras (by Ş.V. Strătilă and L. Zsidó) and, until 2003, was the only comprehensive monograph on the subject. Addressing the students of mathematics and physics and researchers interested in operator algebras, noncommutative geometry and free probability, this revised edition covers the fundamentals and latest developments in the field of operator algebras. It discusses the group-measure space construction, Krieger factors, infinite tensor products of factors of type I (ITPFI factors) and construction of the type III_1 hyperfinite factor. It also studies the techniques necessary for continuous and discrete decomposition, duality theory for noncommutative groups, discrete decomposition of Connes, and Ocneanu's result on the actions of amenable groups. It contains a detailed consideration of groups of automorphisms and their spectral theory, and the theory of crossed products.Covers H. Kosaki's extension of the index to arbitrary factors and F. Rădulescu's examples of non-hyperfinite factors of type IIIλ, λ ∈ (0,1) and of type III1Explains the group-measure space construction in detailDiscusses the main aspects of modular theory with complete proofsMakes the theory accessible to readers having elementary training in operator algebrasTable of ContentsPreface to the second editionPreface to the first edition1.
