Description
Vertex algebras describe two-dimensional conformal field theories in physics. They can be viewed as "chiral quantisations" of symplectic varieties. In this talk, I will explain how to construct vertex algebras over Nakajima quiver varieties by quantum Hamiltonian reduction. As an application, we construct vertex algebras that appear in the context of three- and four-dimensional superconformal field theories. I will also discuss the relation to 3d mirror symmetry and symplectic duality.
