The orbifold DT/PT vertex correspondence
arXiv:2302.02342 · doi:10.1016/j.aim.2025.110222
Abstract
We present an orbifold topological vertex formalism for PT invariants of toric Calabi-Yau 3-orbifolds with transverse singularities. We give a proof of the orbifold DT/PT Calabi-Yau topological vertex correspondence. As an application, we derive an explicit formula for the PT -vertex in terms of loop Schur functions and prove the multi-regular orbifold DT/PT correspondence.
