I am Sven Raum, working as associate professor at Stockholm University in Sweden. My research focuses on operator algebras and their interaction with groups and group-like structures, such as Hecke algebras, groupoids, quantum groups and tensor categories. Important links between operator algebras and these objects are given by unitary representations and the algebras they generate, for example reduced group C*-algebras and group von Neumann algebras.
Currently, at Stockholm University there are my PhD student Garbriel Favre and two postdocs, Ulrik Enstad and Sanaz Pooya, working with me.
From April 2023, I will be W2-professor at the University of Potsdam in Germany.
Besides research mathematics, I enjoy thinking about didactics of higher education. In my free time, I like learning languages, doing sports and cooking.
Seminars
Currently I am one of the organisers of
Stockholm's Wednesday Zoom seminar with topics in algebra, geometry and representation theory.
