%0 Journal Article %T Measures on Banach Manifolds, Random Surfaces, and Nonperturbative String Field Theory with Cut-offs %A Jonathan Weitsman %J Mathematics %D 2008 %I arXiv %X We construct a cut-off version of nonpertubative closed Bosonic string field theory in the light-cone gauge with imaginary string coupling constant. 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. %U http://arxiv.org/abs/0807.2069v1
