Symplectic duality and affine Grassmannian slices

Abstract: Symplectic resolutions are an exciting new frontier of research in geometry and representation theory. One of the most fascinating aspects of this study is symplectic duality: the observation that these resolutions come in pairs with matching properties. The Coulomb branch construction allows us to produce and study many of these dual pairs. I will attempt to survey recent work in this area, particularly focusing on ADE quiver varieties and affine Grassmannian slices.
