Understanding C*-algebras by Inducing Symmetries

Supervisor: Johannes Christensen

Research Area: C*-algebras, ideal structure, groupoid C*-algebras

This project is concerned with the study of groupoid C*-algebras. In recent years groupoid C*-algebras have come to play a prominent role in C*-algebra theory, as it has become evident that they can model many interesting classes of C*-algebras, like C*-algebras arising from dynamical systems. It is in general an open problem to describe the ideal structure of C*-algebras. The aim of the project is to describe the ideal structure and other properties of groupoid C*-algebras, both by developing general theory and by studying specific classes of examples, like the ones arising from dynamical systems.

This PhD position is financed by the Villum Young Investigator grant “Understanding C*-algebras by inducing symmetries” held by Johannes Christensen.

Applicants must have completed a relevant Master’s degree in mathematics by the beginning of the PhD. The topic of the PhD project is C*-algebras, so applicants should have a strong background in analysis, and some background in the field of operator algebras can be an advantage.
