Title:  The noncommutative Laurent phenomenon

Abstract: The composition of polynomials is always a polynomial, but this is not the case for Laurent polynomials containing inverse variables. When Laurent property persists, one talks about the Laurent phenomenon. In the commutative case, the Laurent phenomenon is closely related to the theory of cluster algebras. I will talk about examples of the noncommutative Laurent phenomenon and its connection with the theory of noncommutative cluster algebras. The report is based on joint work with Arkady Berenstein.
