(0, 2) Target-space duality, CICYs and reflexive sheaves Original Research Article

It is shown that the recently proposed target-space duality for (0, 2) models is not limited to models admitting a Landau-Ginzburg description. By studying some generic examples it is established for the broader class of vector bundles over complete intersections in toric varieties. Instead of sharing a common Landau-Ginzburg locus, a pair of dual models agrees in more general non-geometric phases. The mathematical tools for treating reflexive sheaves are provided as well.
