Modularity of open Gromov-Witten potentials of elliptic orbifolds. (English) Zbl 1347.81068
Summary: We study the modularity of the genus zero open Gromov-Witten potentials and its generating matrix factorizations for elliptic orbifolds. These objects constructed by Lagrangian Floer theory are a priori well-defined only around the large volume limit. It follows from modularity that they can be analytically continued over the global Kähler moduli space.
