Two-dimensional twisted sigma models and the theory of chiral differential operators
In this paper, we study the perturbative aspects of a twisted version of the two-dimensional (0, 2) heterotic sigma model on a holomorphic gauge bundle E over a complex, hermitian manifold X.We show that the model can be naturally described in terms of the mathematical theory of "Chiral Differential Operators".In …
