Abstract:

Given a singularity with a crepant resolution, a symmetry of the derived category of coherent sheaves on the resolution may often be constructed. I discuss work in progress on general constructions of such symmetries for hypersurface singularities. This builds on previous results with Segal, and is inspired by work of Bodzenta-Bondal.

Fermionic Higher-form Symmetries
AbstractIn this talk, we propose a new type of global symmetries: the fermionic higher-form symmetries. We discuss examples with fermionic higher-form symmetries as well as the gauging and breaking of such symmetries. The talk is based on the work 2303.12633 with Yi Zhang

Moduli Spaces of Solutions to Non-Linear PDES in (Derived) Differential Geometry
AbstractMany moduli spaces in geometry and physics, like those appearing in symplectic topology, quantum gauge field theory and in relation to homological mirror symmetry, are constructed as parametrizing spaces of solutions to nonlinear elliptic differential operators modulo symmetries of the underlying theory. A plethora of difficulties arise in constructing such spaces; for instance, the spa...
