Abstract

In arXiv:2011.08830 we established a series of correspondences relating five enumerative theories of log Calabi-Yau surfaces, i.e. pairs (Y,D)(Y,D) with YY a smooth projective complex surface and D=D1++DlD=D_1+\dots +D_l an anticanonical divisor on YY with each DiD_i smooth and nef. In this paper we explore the generalisation to YY being a smooth Deligne-Mumford stack with projective coarse moduli space of dimension 2, and DiD_i nef Q\mathbb{Q}-Cartier divisors. We consider in particular three infinite families of orbifold log Calabi-Yau surfaces, and for each of them we provide closed form solutions of the maximal contact log Gromov-Witten theory of the pair (Y,D)(Y,D), the local Gromov-Witten theory of the total space of iOY(Di)\bigoplus_i \mathcal{O}_Y(-D_i), and the open Gromov-Witten theory of toric orbi-branes in a Calabi-Yau 3-orbifold associated to (Y,D)(Y,D). We also consider new examples of BPS integral structures underlying these invariants, and relate them to the Donaldson-Thomas theory of a symmetric quiver specified by (Y,D)(Y,D), and to a class of open/closed BPS invariants.
