If you have a question about this talk, please contact Valentin HÃ¼bner. While working on problems in logic in the 1960’s, Richard J. Thompson discovered a family of groups, now called F, T and V, which have simple definitions and give rise to many examples as well as tantalising problems. The groups were subsequently found to occur in several other guises: in work on infinite simple groups, homotopy and shape theory, group co-homology, dynamical systems, knot theory and analysis, and have been generalised in several different ways. I will describe F,T and V, in a few different ways, outline some important features and describe one way in which they arise as dynamical systems.
