String Math Seminar: Justin Hilburn (Perimeter Institute) “2-categorical 3d mirror symmetry and symplectic duality”
–
Abstract: By now it is known that many interesting phenomena in geometry and representation theory can be understood as aspects of mirror symmetry of 3d N=4 SUSY QFTs. Such a QFT is associated to a hyper-Kähler manifold X equipped with a hyper-Hamiltonian action of a compact Lie group G and admits two topological twists. The first twist, which is known as … Read More
