The local-orbifold correspondence for simple normal crossings pairs

Abstract

For $X$ a smooth projective variety and $D=D_1+\dots +D_n$ a simple normal crossings divisor, we establish a precise cycle-level correspondence between the genus zero local Gromov-Witten theory of the bundle ${\oplus }_{i=1}^n{\mathcal{O}}_X(-D_i)$ and the maximal contact Gromov-Witten theory of the multi-root stack $X_{D,\vec{r}}$. 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.
