Interval Exchange Transformations

by Jon Chaika | Rice University
Time: 16:10 — 17:00  (Wednesday, Feb. 24, 2010)
Location: BA6183, Bahen Center, 40 St. George St.
Abstract:
This talk is on a generalization of rotations of the circle, Interval Exchange Transformations. It will present some of the major techniques for their study and reasons for interest in them. Topological mixing, Diophantine properties, Generic disjointness, and Hausdorff dimensions of ergodic measures will be mentioned.
