We’re very excited to welcome Emmanuel Breuillard (University of Cambridge), as a Heilbronn Virtual Visiting Professor.

Title: Approximate groups

Abstract: Symmetry is one of the most fundamental concepts of science and mathematics. Group theory is the field of mathematics devoted to its study. In this lecture we will discuss various situations where symmetry is present only partially and where a notion approximate symmetry arises naturally. In group theory this leads to the notion of approximate group, which has been much studied in the last twenty years in connection with various fields including additive combinatorics, harmonic and fractal analysis, asymptotic finite group theory, geometric group theory, ergodic theory and even logic and model theory. The lecture will introduce this concept and present some recent developments.
