BIMSA > An introduction to $C^*$-algebras and $K$-theory \(ICBS\)
An introduction to $C^*$-algebras and $K$-theory
This course offers an introductory exploration of the fundamental principles of $C^*$-algebras and $K$-theory with emphasis on classification of $C^*$-algebras using K-theoretic data. The first part of this course delves into the essential aspects of $C^*$-algebras, which are helpful to introducing $K$-theory. These include the Gelfand representation, Gelfand-Naimark-Segal construction, and Gelfand-Naimark representation. The second part is devoted to the introduction of $K_0$-groups for $C^*$-algebras, covering their basic properties and exploring Elliott's classification of AF-algebras. Finally, the course proceeds to introduce $K_1$-groups. (For those who have taken the course with the same title in the autumn semester of 2023, the essential part of this course remains the same, while you can find discussions of new topics and adapted expositions of the familiar parts to new discourses along the process.)

Lecturer Intro
He graduated from the University of Tokyo in 2018, and then became an associate research fellow at University of Tokyo. After finishing his postdocteral position at East China Normal University in 2022, He joined BIMSA as an assistant professor in 2023. He's recent research interests lie in classification theory of C*-algebras, C*-dynamical systems and topological dynamical systems.
