Karin Baur: Cluster algebra structure of Grassmannians and related cluster categories

 Cluster algebra structure of Grassmannians and related cluster categories

Karin Baur, KFU Graz 

Abstract:

We first describe the cluster algebra structure of the coordinate ring of the Grassmannian Gr(k,n) arising from triangulations (Fomin-Zelevinsky) and from Postnikov diagrams (Scott). We then discuss related work with King and Marsh on module categories to present the cluster category side of this picture in terms of dimer models with boundary.
