Local Pandharipande–Thomas invariants equal local Gopakumar–Vafa invariants
Let be as in the definition of local Gopakumar–Vafa invariants, let be an effective one-cycle class, and let . For , let and denote the local stable-pair and local Gopakumar–Vafa invariants. Local PT/GV correspondence. One should have
This is the local form of the PT/GV correspondence and would identify the two constructible-function-valued theories; the source gives no resolution.
