Abstract: (Elsevier)
A diagrammatic operator method based on Fock space formulations of 3-string vertices is developed for computing the integration measure for open or closed string S -matrix to arbitrary loop order. The proposed vertex does not triangulate the moduli space, thus a single diagram incorporates a number of string field theory diagrams. However, the formalism does not naturally lead to a single cover of moduli space, and the restriction to the fundamental domain must be put in by hand, as in the Polyakov functional integral approach.- MODEL: STRING
