One parameter family of exact solutions in general relativity with a scalar field has been found using the Liouville metric. The scalar field potential is exponential and bounded from below. This model is interesting because, in particular, the solut

New one parameter family of exact solutions in General Relativity with a scalar field is found. The metric is of Liouville type which admits complete separation of variables in the geodesic Hamilton-Jacobi equation. This solution exists for the expon

We consider general relativity with cosmological constant minimally coupled to the electromagnetic field and assume that the four-dimensional space-time manifold is a warped product of two surfaces with Lorentzian and Euclidean signature metrics. Fie
