摘要
An anisotropic (Bianchi type I) cosmology is considered in the four-dimensional NS-NS sector of low-energy effective string theory coupled to a dilaton and an axion-like -field within a de Sitter-Einstein frame background. The time evolution of this Universe is discussed in both the Einstein and string frames.
