Abstract
The cosmological equations of a gravitational field, minimally coupled with a scalar field, are exactly integrated, provided that the potential ofthe scalar field belongs to a special class of exponentials. A particular solution is given, exhibiting the damping of the effective cosmological constant and a power-law inflation.File in questo prodotto:
