Measures on Banach Manifolds, Random Surfaces, and Nonperturbative String Field Theory with Cut-offs
arXiv:0807.2069
Abstract
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.
