Title: Symplectic Singularities
Speaker: Naomi Rosenberg
Abstract: Many singular varieties arising in algebraic geometry, such as those obtained via Hamiltonian reductions, are closely related to symplectic geometry. In this talk, we will introduce Beauville’s notion of symplectic singularities, which provides a way of studying symplectic geometry in the singular setting. We will study an explicit example arising from Hamiltonian reduction and construct a symplectic resolution of it. If time permits, we will also briefly mention Coulomb branches of quiver gauge theories as another source of symplectic singularities.
