Applications of the UCT for C*-algebras

University of Copenhagen 
October 2nd to October 6th, 2017

This masterclass will focus on KK-theory and the Universal Coefficient Theorem, with a special regard towards applications to the structure and classification theory of nuclear C*-algebras. Further topics, such as equivariant extensions of KK-theory for C*-algebras over topological spaces or with group actions, will also be explored.

Lecture series:

  • Marius Dadarlat (Purdue University)
    "A friendly introduction to KK-theory and the UCT"
  • Wilhelm Winter (Westfälische Wilhelms-Universität Münster)
    "Structure and classification of nuclear C*-algebras: The role of the UCT"

Slides & notes:

Update: Notes for all talks of the masterclass are available here.
