Since 1980s, Donaldson theory plays an eminent role in the development of topology of four manifolds. In 1990s, Donaldson and Thomas proposed a higher dimensional analogue (DT-theory) of Donaldson theory for four manifolds. In this talk, I will introduce briefly DT-theory of Calabi-Yau 3-folds, its conjectural relation with GW theory, and the joint work with Jun Li on the degeneration formula of DT-invariants.
