Chow Rings of Fine Quiver Moduli are Tautologically Presented

Representation Theory 2015-01-16 v2 Algebraic Geometry

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.
