The Quantum Lefschetz Hyperplane Principle Can Fail for Positive Orbifold Hypersurfaces

Abstract

We show that the Quantum Lefschetz Hyperplane Principle can fail for certain orbifold hypersurfaces and complete intersections. It can fail even for orbifold hypersurfaces defined by a section of an ample line bundle.
