Orbifolds, Quantum Cosmology, and Nontrivial Topology
Helio V. Fagundes, Teofilo Vargas
In order to include nontrivial spatial topologies in the problem of quantum creation of a universe, it seems to be necessary to generalize the sum over compact, smooth 4-manifolds…
The Energy of Bianchi Type I and II Universes in Teleparallel Gravity
Lau Loi So, T. Vargas
For certain models, the energy of the universe which includes the energy of both the matter and the gravitational fields is obtained by using the quasilocal energy-momentum in tele…
Goedel type solution in teleparallel gravity
Yu. N. Obukhov, T. Vargas
The stationary cosmological model without closed timelike curves of Gödel type is obtained for the ideal dust matter source within the framework of the teleparallel gravity. For a…
Quantum Creation of a Universe with Quasi-Hyperbolic Spatial Sections
Helio V. Fagundes, Teofilo Vargas
We calculate the probability of creation of a universe with space topology , where is the circle and is a compact hyperbolic surface of genus $g\…
The energy of the universe in teleparallel gravity
T. Vargas Auccalla
The teleparallel versions of the Einstein and the Landau-Lifshitz energy-momentum complexes of the gravitational field are obtained. By using these complexes, the total energy of t…
