Genus one mirror symmetry for intersection of two cubics in ${\mathbb{P}}^5$

Abstract

This paper establishes BCOV-type genus one mirror symmetry for the intersections of two cubics in ${\mathbb{P}}^5$. The proof applies previous constructions of the mirror family by the second author and computations of genus one Gromov-Witten invariants by A. Popa. The approach adapts the strategy used for hypersurfaces, as developed by the first author and collaborators, but addresses the distinct geometry involved. A key feature is a systematic usage of toric techniques and related computer aided calculations to determine seemingly otherwise inaccessible invariants.
