Exact solutions using power law scalar potential in the Saez-Ballester-K-essence like theory
J. Socorro, A. Gil-Ocaranza, Ximena López-Mujica +1
We investigate a K-essence like cosmological model whose scalar-field potential is constructed from a negative power-law Sáez--Ballester potential. By means of a suitable field red…
Iso-spectral potential and inflationary quantum cosmology
A. Garcia, W. Guzman, M. Sabido +1
Using the factorization approach of quantum mechanics, we obtain a family of isospectral scalar potentials for power law inflationary cosmology. The construction is based on a scat…
Plebański-Demiański-like solutions in metric-affine gravity
A. Garcia, F. W. Hehl, C. Laemmerzahl +2
We consider a (non--Riemannian) metric--affine gravity theory, in particular its nonmetricity--torsion sector ``isomorphic'' to the Einstein--Maxwell theory. We map certain Einstei…
The Gauge Theory of the de-Sitter Group and Ashtekar Formulation
J. A. Nieto, O. Obregón, J. Socorro
By adding the Pontrjagin topological invariant to the gauge theory of the de Sitter group proposed by MacDowell and Mansouri we obtain an action quadratic in the field-strengths, o…
