Abstract: Hybrid models are a class of Landau-Ginzburg orbifolds fibred over some base manifold. They naturally arise in limiting regions of the stringy Kahler moduli spaces of Calabi-Yaus and as phases of the associated gauged linear sigma models (GLSMs). We compute genus zero correlators for hybrids with one and two Kahler parameters. These correlators are generalisations of GW/FJRW invariants. We use GLSM techniques, combined with the physics formulation of hybrids, to extract the invariants from I/J-functions. This is joint work with D. Erkinger.
