Cluster algebras and singular supports of perverse sheaves

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.

Keywords: Cluster algebras, perverse sheaves, singular supports
