Group theory is the field of mathematics devoted to its study. In this l ecture we will discuss various situations where symmetry is present only p artially and where a notion approximate symmetry arises naturally. In grou p theory this leads to the notion of approximate group\, which has been mu ch studied in the last twenty years in connection with various fields incl uding additive combinatorics\, harmonic and fractal analysis\, asymptotic finite group theory\, geometric group theory\, ergodic theory and even log ic and model theory. The lecture will introduce this concept and present s ome recent developments.\n LOCATION:https://researchseminars.org/talk/HeilbronnVVP/1/ END:VEVENT END:VCALENDAR
