Quantum corrections for a cosmological string solution
Abstract
We investigate quantum corrections for a cosmological solution of the string effective action. Starting point is a classical solution containing an antisymmetric tensor field, a dilaton and a modulus field which has singularities in the scalar fields. As a first step we quantize the scalar fields near the singularity with the result that the singularities disappear and that in general nonperturbative quantum corrections form a potential in the scalar fields.
