Geometrical framework for picture changing operators in the pure spinor formalism


Abstract in English

It is well known in NSR string theory, that vertex operators can be constructed in various ``pictures. Recently this was discussed in the context of pure spinor formalism. NSR picture changing operators have an elegant super-geometrical interpretation. In this paper we provide a generalization of this super-geometrical construction, which is also applicable to the pure spinor formalism.
