Cosmological solutions with dilaton and maximally symmetric space in string theory
arXiv:hep-th/9203033 · doi:10.1142/S0218271892000112
Abstract
We discuss time - dependent solutions of the leading order string effective equations for a non-zero central charge deficit and curved maximally symmetric space. Some regular solutions are found for the case of non-trivial antisymmetric tensor and vector backgrounds (in various dimensions) and negative spatial curvature. It remains an open question which conformal theories are exact generalisations of these solutions.
