Noncommutative analysis on groups and quantum groups

par Dupré Emilie - publié le , mis à jour le


Period : January 2020 - December 2023.

Description : This project deals with noncommutative (abbreviated to NC) analysis of topics related to multipliers. NC analysis is a new research direction emerging from operator spaces, quantum probability and NC harmonic analysis.

Fourier and Schur multipliers are at the intersection of these areas and play a key role in recent research motivated by concepts and problems from operator algebras and geometric group theory. They are natural examples of maps on NC Lp-spaces and intimately linked with NC functional inequalities. They are also used to formulate geometric properties (weak amenability, Haagerup property) of groups and quantum groups in terms of von Neumann algebras. Interactions between different approaches at the frontiers of NC analysis have given impressive discoveries. Our project will allow to open a vast avenue of perspectives and to reach a new level of development in these competitive fields by joining competences in combinatorics, geometric group theory and operator spaces.

Postdoc position

Deadline : May 15, 2020


We are now accepting applications for a postdoctoral research fellowship (without teaching duty) for the academic year 2020-2021 (starting date : Sept. 1, 2020, which may be delayed for 1 or 2 months) in the framework of the project. We are looking for applicants who received their Ph.D. recently (after Sept. 1, 2015) or will receive it until September or October 2020.

The fellow is expected to carry out a research project on the topics of the project ANR-ANCG (noncommutative harmonic analysis, operator spaces, noncommutative Lp-spaces, quantum probability, topological quantum groups and their operator algebras) at the Laboratoire de Mathématiques de Besançon (Université de Bourgogne Franche-Comté). The fellowship provides a salary of about 1.900 euro per month after taxes.
