Black hole formation by a scalar field
D. E. Afanasev, M. O. Katanaev
The Liouville solution in General Relativity with a scalar field is discussed. This solution is invariant with respect to global Lorentz transformations, and dependence on time can…

Geodesics and Global Properties of the Liouville Solution in General Relativity with a Scalar Field
D. E. Afanasev, M. O. Katanaev
One parameter family of exact solutions in General Relativity with a scalar field has been found using the Liouville metric. The scalar field potential has exponential form. This m…

Was there a Big Bang?
D. E. Afanasev, M. O. Katanaev
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…
