I am Sven Raum, chair of algebra at the University of Potsdam in Germany. 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, the group consists of my PhD student Garbriel Favre and postdoc Sanaz Pooya.

I am member of the MATH+ Faculty.

Besides research mathematics, I enjoy thinking about didactics of higher education. In my free time, I like learning languages, doing sports and cooking.

Seminar

The workgroup's seminar GOAT (Gruppen- und Operatoralgebren-Treffen) currently takes place Thursdays 10:15 - 11:45 in room 0.26 of house 10 on campus Golm.

Wednesday Zoom Seminar

During the Corona pandemic, the Wednesday Zoom Seminar combined speakers in algebraic geometry, group theory and operator algebras.

All abstracts can be found in the SMC calender: Link.

HAOART Seminar

Due to the Corona pandemic, our seminar on Harmonic Analysis, Operator Algebras and Representation Theory (pronounced "Howard") is was suspended and eventually discontinued.

All abstracts can be found in the SMC calender: Link.

Publications

All my publications can be found on MathSciNet, zbMATH and ArXiv.
