Abstract

We discuss the relation between unintegrated and integrated vertex operators in string worldsheet theory, in the context of BV formalism. In particular, we clarify the origin of the Fradkin-Tseytlin term. We first consider the case of bosonic string, and then concentrate on the case of pure spinor superstring in AdS₅× S⁵. In particular, we compute the action of b₀ - b₀ on the beta-deformation vertex. As a by-product, we formulate some new conjectures on general finite-dimensional vertices.
