QM Research Seminar: Classical cohomological field theory

Speaker: Shuhan Jiang (Max Planck Institute, Leipzig)


Abstract:

In this talk, I will introduce a geometric framework for classical cohomological field theories (CohFTs) using G^{\star} algebras and variational bicomplexes. This framework enables a mathematical interpretation of scalar and vector supersymmetries, along with a systematic classification of solutions to the descent equations for CohFTs. Furthermore, I will provide a BV-BFV extension of this framework, illustrating its application through the (fully extended) Donaldson-Witten theory.
