Cartan C*-subalgebras and noncommutative dynamics
IMPAN (Warsaw, Poland) 25-28 November 2019
General information:
Celebrated Renault's result from 2008 states that all commutative Cartan C*-subalgebras
correspond to twisted topological groupoids.
This provides a strong link between operator algebras and dynamical systems,
that made Cartan subalgebras one of central objects of study in the theory of C*-algebras.
Questions of existence, uniqueness, properties and structure of Cartan inclusions play a predominant role in a number of problems,
such as the UCT problem, C*-rigidity of dynamical systems, reconstruction of groupoids,
classification of endomorphisms of Cuntz algebras, description of automorphisms groups of graph C*-algebras, and so on.
The aim of the meeting is an exchange of ideas and report on recent advances
in the theory evolved around Cartan subalgebras.
We plan a few lectures and plenty
time for reasearch and discussions.
