Abstract
In twisted conformal field theory the basic fields have branch cut singularities on the relevant Riemann surfaces. We present a geometrical framework describing these fields which is alternative to the standard method of coverings. This leads to a non-trivial generalization of the Serre and Riemann-Roch theory. We further introduce the notion of twisted grassmanians and define the appropriate generalization of the Krichever map in this setting. © 1989.File in questo prodotto:
