Matrix mutations and Dynkin diagrams
refreshments at 3:45pm
This talk is about combinatorial aspects of the theory of cluster algebras
initiated by Sergey Fomin and myself three years ago. We shall discuss a
family of piecewise-linear transformations (called mutations) of integer
matrices. The classification of matrices with certain finiteness property
preserved under mutations turns out to provide a new instance of the
famous Cartan-Killing classification.
