Abstract:
It is pointed out that Cremmer and Gervais' version of the three-string vertex can be derived as a limit of a path-integral already familiar in dual-resonance theory. Our basic language which will figure in this paper is the harmonic dual-position vector (stream function) over a two-dimensional domain, so that the proof is carried out within the framework of the Dirichlet problem. The vertex for large proper-time is also discussed from the same point of view.
