On a possible solution for the Polonyi problem in string cosmology
M. C. Bento, O. Bertolami
Abstract
We establish the main features of homogeneous and isotropic dilaton, metric and Yang-Mills configurations in a cosmological framework. We identify a new energy exchange term between the dilaton and the Yang-Mills field which may lead to a possible solution to the Polonyi problem in 4-dimensional string models.
