Colloquium: Tuesday, December 26, 2 pm. Speaker: Sergei Fomin (Michigan). Title: “Morsifications and mutations”.
I will discuss a surprising connection between singularity theory and cluster algebras, specifically between (1) the topology of isolated singularities of plane curves and (2) the mutation equivalence of the quivers associated with their morsifications. Joint work with Pavlo Pylyavskyy and Eugenii Shustin
