Beltrami differentials, conformal models and their supersymmetric generalizations
Beltrami differentials, conformal models and their supersymmetric generalizations
Conformally invariant couplings of two-dimensional field theories to gravity can be formulated either in a Riemannian surface or manifold (metric) framework. After a detailed presentation of the Riemannian surface approach (and comparison with the metric formalism), the authors develop its supersymmetric generalization. Super Beltrami differentials are introduced without any reference …
