Cluster algebras and singular supports of perverse sheaves (1301.5079v2)
Published 22 Jan 2013 in math.QA, math.RA, and math.RT
Abstract: We propose an approach to Geiss-Leclerc-Schroer's conjecture on the cluster algebra structure on the coordinate ring of a unipotent subgroup and the dual canonical base. It is based on singular supports of perverse sheaves on the space of representations of a quiver, which give the canonical base.
