Chow Rings of Fine Quiver Moduli are Tautologically Presented

Published 11 Jul 2013 in math.RT and math.AG | (1307.3066v2)

Abstract: A result of A. King and C. Walter asserts that the Chow ring of a fine quiver moduli space is generated by the Chern classes of universal bundles if the quiver is acyclic. We will show that defining relations between these Chern classes arise geometrically as degeneracy loci associated to the universal representation.
