We show that the partition function is a continuous function of the string coupling constant, and conjecture a relation between the formal power series expansion of this partition function and Riemann Surfaces.Mathematical PhysicsDifferential GeometryMeasures on Banach Manifolds, Random Surfaces, and Nonperturbative String Field Theory with Cut-offstext
