Lagrangian Intersections, Symplectic Reduction and Kirwan Surjectivity

Naichung Conan Leung, Ying Xie, Yu Tung Yau

Given a smooth holomorphic symplectic variety $X$ with a Hamiltonian $G$-action, $G$-invariant Lagrangians $C^{\prime }s$ induce Lagrangians in the symplectic quotient $X//G$. Given clean…
