The local-orbifold correspondence for simple normal crossings pairs

Algebraic Geometry 2023-08-22 v3

Abstract

For XX a smooth projective variety and D=D1++DnD=D_1+\ldots+D_n a simple normal crossings divisor, we establish a precise cycle-level correspondence between the genus zero local Gromov-Witten theory of the bundle i=1nOX(Di)\oplus_{i=1}^n \mathcal{O}_X(-D_i) and the maximal contact Gromov-Witten theory of the multi-root stack XD,rX_{D,\vec{r}}. The proof is an implementation of the rank reduction strategy. We use this point of view to clarify the relationship between logarithmic and orbifold invariants.
