Title:

Towards a complexification of Donaldson-Witten TQFT

Abstract：

Donaldson-Thomas theory on Calabi-Yau 4-folds (DT4) is a complexification of Donaldson theory on 4-manifolds. In this talk, we will discuss a complexification of Donaldson-Witten TQFT. This establishes a degeneration formula of DT4 invariants and a Gromov-Witten type theory for critical loci (quivers with potentials).
