Kirwan surjectivity for quiver varieties
For algebraic varieties defined by hyperk¨ahler or, more generally, algebraic symplectic reduction, it is a long-standing question whether the “hyperk¨ahler Kirwan map” on cohomology is surjective. We resolve this question in the affirmative for Nakajima quiver varieties. We also establish similar r...
