Floris Elzinga

Doctoral Research Fellow

About me

PhD candidate in the Operator Algebras group at UiO, supervised by Makoto Yamashita. My thesis has been approved for defense, which will take place on the 27th and 28th of June.

I am a member of the organizing committee for the 2022 edition of YMC*A. The website is here.

I like to be somewhat aware of what my colleagues are working on, so together with Emilie Elkiær I organize a monthly seminar for young researchers at the department where we give short and accessible expository talks. You can sign up for the mailing list here.

Academic Interests

Generally I am interested in (noncommutative) mathematics inspired by quantum theory.

At the moment I work mainly on von Neumann algebras coming from compact quantum groups. For example, it is interesting to try and distinguish these from von Neumann algebras coming from 'genuine' groups, through strong 1-boundedness for instance.

Another project I've worked on is to search for clues in Poisson–Lie theory on how to quantize real simple Lie groups.
