Universal families of twisted cotangent bundles

Peter Crooks

Given a complex algebraic group $G$ and complex $G$ -variety $X$ , one can study the affine Hamiltonian Lagrangian (AHL) $G$ -bundles over $X$ . Lisiecki indexes the isomorphism classe…

Abelianization and the Duistermaat-Heckman theorem

Peter Crooks, Jonathan Weitsman

Fix a compact connected Lie group $G$ with Lie algebra $g$ , as well as a strong Gelfand-Cetlin datum on $g^{*}$ . Let us also fix a connected symplectic manifold…
