Pure Maths Colloquium: The geometry of Brauer graph algebras and cluster mutation

Presented by Sibylle Schroll , University of Leicester

10 March 2014 16:00 in CM221

In this talk we will show that ribbon graphs have a Brauer graph structure and that any compact oriented marked surface will give rise to a unique Brauer graph algebra up to derived equivalence. The derived equivalences are induced by flips of diagonals in ideal triangulations of the surface. In the case of a disc with marked points we will give a dual construction in terms of Brauer tree algebras. This is joint work with Robert Marsh.
