An Introduction to C*-Algebras and the Classification Program

Karen R. Strung is a researcher in the Department of Abstract Analysis at the Institute of Mathematics of the Czech Academy of Sciences, in Prague, Czechia. I study the classification and structure of C*-algebras and their connections to dynamical systems.

"The book is extremely readable. ... The book is also self-contained, and cross-references to results and definitions in the text are clear and precise. ... this book is a very welcome contribution to the literature. ... On the whole, the book is well written and engaging." (Elizabeth Anne Gillaspy, Mathematical Reviews, March, 2023)

"The book under review provides an overview of this classification theorem, together with a thorough introduction to the general theory of C*-algebras." (Zhuang Niu, zbMATH 1479.46003, 2022)
