On triprojective dg algebras

Speaker: Professor Bernhard Keller

Venue: Lecture Hall 202, Haina Complex Building 2, Zijingang Campus

Abstract: For a Dynkin quiver Q, the triprojective (dg) algebra associated with Q is glued together from three copies of the corresponding preprojective (dg) algebra. The category of Gorenstein projective dg modules over the triprojective dg algebra is expected to categorify Goncharov-Shen's cluster variety of triples of flags of the type of Q and this is our main motivation for considering them.
