THE 3-VERTEX IN THE CLOSED HALF-STRING FIELD-THEORY AND THE GENERAL GLUING AND RESMOOTHING THEOREM

In this letter we prove that the half-string three-vertex in closed st ring field theory satisfies the general gluing and resmoothing theorem . We also demonstrate how one calculates amplitudes in the half-string approach to closed string held theory, by working out explicitly a fe w simple three-amplitudes.
