Torus-Equivariant Chow Rings of Quiver Moduli

We compute rational equivariant Chow rings with respect to a torus of quiver moduli spaces. We derive a presentation in terms of generators and relations, use torus localization to identify it as a subring of the Chow ring of the fixed point locus, and we compare the two descriptions.

I would like to thank Markus Reineke and Silvia Sabatini for inspiring discussions on this subject. I also want to thank the two referees for their valuable comments. At the time this research was conducted, I was supported by the DFG SFB/TR 191 "Symplectic structures in geometry, algebra, and dynamics".
