Title:Cluster algebras
Seminar:Department of Mathematics Colloquium
Speaker:Sergey Fomin, University of Michigan
Cluster algebras were introduced in the Spring of 2000 in a joint work with Andrei Zelevinsky. They arise in various algebraic and geometric contexts, with combinatorics providing a unifying framework. My presentation of the basic definitions and results of this emerging theory will be guided by two sets of examples: coordinate rings of classical algebraic varieties, and cluster algebras associated with bordered oriented surfaces with marked points. I will present results by A. Berenstein, F. Chapoton, C. Geiss, B. Leclerc, J. Schroer, J. Scott, M. Shapiro, D. Thurston, W. Thurston, A. Zelevinsky, and myself.
