Geodesics and Global Properties of the Liouville Solution in General Relativity with a Scalar Field

Autor: Afanasev, D. E., Katanaev, M. O.

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

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
