Donaldson–Thomas (DT) and Pandharipande–Thomas (PT) invariants are enumerative invariants attached to Calabi–Yau 3-folds. They are related by a wall-crossing type formula called the “DT/PT correspondence”.

After a general introduction, we will discuss a variation of this correspondence, relating the “local” DT and PT invariants, encoding the contribution of a single smoooth curve to the full (classical) invariants.
