Andrea Ricolfi: The DT/PT correspondence for smooth curves
Time: Wed 2017-11-22 13.15 - 15.00
Location: Room 3418, KTH
Participating: Andrea Ricolfi (Stavanger)
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.
