Interval exchange transformations
Abstract: Interval exchange transformations are invertible, piecewise
order preserving isometries of the unit interval with finitely many
discontinuities. Starting from rotations of the circle, which they
generalize, this talk will present their connections to flows on flat
surfaces, rational billiards and symbolic coding. Recent results on
diophantine approximation for interval exchange transformations will be
presented.
