A remark on Leclerc's Frobenius categories

Published 14 Sep 2017 in math.RT and math.CT | (1709.04785v1)

Abstract: Leclerc recently studied certain Frobenius categories in connection with cluster algebra structures on coordinate rings of intersections of opposite Schubert cells. We show that these categories admit a description as Gorenstein projective modules over an Iwanaga-Gorenstein ring of virtual dimension at most two. This is based on a Morita type result for Frobenius categories.
