DESCRIPTION: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 defi
nitions and give rise to many examples as well as
tantalising problems. The groups were subsequently
found to occur in several other guises: in work o
n infinite simple groups\, homotopy and shape theo
ry\, group co-homology\, dynamical systems\, knot
theory and analysis\, and have been generalised in
several different ways.\n\nI will describe F\,T a
nd V\, in a few different ways\, outline some impo
rtant features and describe one way in which they
arise as dynamical systems.
