Conformal invariance of (0, 2) sigma models on Calabi-Yau manifolds

Name: Work Video:
Duration: 3 min 30 s
Description: Long ago, Nemeschansky and Sen demonstrated that the Ricci-flat metric on a Calabi-Yau manifold could be corrected, order by order in perturbation theory, to produce a conformally invariant (2,2) nonlinear sigma model. Here we extend this result to (0,2) sigma models for stable holomorphic vector bundles over Calabi-Yaus.
