Title :  Markov chains coming from card shuffling

Speaker:  Matthieu Josuat-Verges, Research fellow at CNRS, affected to IRIF (Institute for Research in Fundamental Computer Science), Paris-Cité University, France.

Abstract: Riffle shuffle is a natural way to shuffle a deck of cards: cut in two blocks, and shuffle the two blocks by preserving their relative order.  Successive riffle shuffles give a Markov chain on the symmetric group that converges to the uniform distribution.  Bayer and Diaconis have precise results concerning the convergence rate.  I will outline the general results of Bidigare, Hanlon and Rockmore concerning a generalization in the context of hyperplane arrangement.  I will also explain the connection to my work on subalgebras of the descent algebras (joint work with Amy Pang).
