Abstract

Given a (projective) conifold transition of smooth projective threefolds from $X$ to $Y$, we show that if the Gromov--Witten/Pandharipande--Thomas descendent correspondence holds for the resolution $Y$, then it also holds for the smoothing $X$ with stationary descendent insertions. As applications, we show the correspondence in new cases. This is joint work with Sz-Sheng Wang.

Conifold transitions and heterotic dualities
AbstractThe first part of this talk will review recent work describing a geometric process by which gauge bundles can traverse conifold transitions in heterotic theories. These transitions lead to seemingly dual heterotic compactifications, generalizing the (0,2) target space duality seen in GLSMs. The second part of this talk will describe ongoing work aimed at investigating whether this is a ...

The DonovaThe Donovan-Wemyss Conjecture via the Derived Auslander-Iyama CorrespondenceAbstractThe Donovan-Wemyss Conjecture predicts that the isomorphism type of an isolated compound Du Val singularity R that admits a crepant resolution is completely determined by the derived-equivalence class of any of its contraction algebras. Crucial results of August and Hua-Keller reduced the conjecture to...
