On the symplectic structure of instanton moduli spaces

Roger Bielawski, Victor Pidstrygach

We study the complex symplectic structure of the quiver varieties corresponding to the moduli spaces of SU(2) instantons on both commutative and non-commutative R^4. We identify gl…

Gelfand-Zeitlin actions and rational maps

Roger Bielawski, Victor Pidstrygach

We observe that the analogue of the Gelfand-Zeitlin action on gl(n,C), which exists on any symplectic manifold M with an Hamiltonian action of GL(n,C), has a natural interpretation…
