Wall-crossing in genus-zero hybrid theory

Abstract The hybrid model is the Landau–Ginzburg-type theory that expected, via Landau–Ginzburg/ Calabi–Yau correspondence, to match Gromov–Witten of a complete intersection in weighted projective space. We prove wall-crossing formula exhibiting dependence genus-zero on its stability parameter, generalizing work [21] for quantum singularity and paralleling Ciocan-Fontanine–Kim [7] quasimaps. This completes proof Landau– Ginzburg/Calabi–Yau correspondence intersections hypersurfaces same degree, as well all-genus [11].
