Title: Noncommutative Recursions and the Laurent Phenomenon

Speaker: **Matthew Russell**, Rutgers University

Date: Thursday, November 21, 2013 5:00pm

Location: Hill Center, Room 705, Rutgers University, Busch Campus, Piscataway, NJ

Abstract:

We exhibit a family of sequences of noncommutative variables, recursively defined using monic palindromic polynomials in Q[x], and show that each possesses the Laurent phenomenon. This generalizes a conjecture by Kontsevich.
