Title:
Cluster algebras associated with bordered surfaces
Abstract:
Coordinatizations of decorated Teichmuller spaces, introduced by
Robert Penner, naturally produce a class of cluster algebras associated
with bordered Riemann surfaces with marked points. I will report on an
ongoing project, joint with Michael Shapiro and Dylan Thurston, dedicated
to the study of these cluster algebras.
