Moduli of special Lagrangians with boundary, II: Lagrangian Flux and Affine Structures

This article continues the study of moduli spaces of special Lagrangians with boundary in a Calabi–Yau manifold. The moduli space was shown to be a smooth finite-dimensional manifold in the prequel arXiv:2503.6321918. This article investigates geometric structures on the moduli space of special Lagrangians with boundary and constructs a pair of special affine structures and a Hessian metric on this moduli space.
