operator algebras representation theory

Audience:	Researchers in the topic
Seminar series time:	Thursday 11:15-12:45 in your time zone, UTC
Organizer:	Ralf Meyer*

This seminar will focus on C*-hulls of *-algebras with respect to a class of integrable representations, roughly following my 2017 paper Representations of *-algebras, C*-hulls, local-global principle, and induction. It takes place in a hybrid format during the winter term 2022-3. The lectures will usually be streamed and recorded. The streams are available at the URL streaming.math.uni-goettingen.de where you have to choose the right room (Sitzungszimmer) I plan that someone in the audience opens the big blue button room on some electronic device in the lecture room to relay questions and comments from outside speakers.
