Noncommutative Geometry at IWOTA 2023

We are organizing a special session on Noncommutative Geometry during the 34th International Workshop on Operator Theory and its Applications (IWOTA 2023) at the University of Helsinki, Finland.

Dates: July 31 – August 4, 2023

Description:

During the last few years, the mathematical field of noncommutative geometry has witnessed a lot of scientific activity. This includes the intriguing development of unbounded KK-theory and the recent analysis of several different quantum metric spaces, with exciting links to operator algebras. These two main research themes -unbounded KK-theory and quantum metric spaces- will be the focus of the present special session on noncommutative geometry.
