Cosmological Solutions with Torsion in a Model of de Sitter Gauge Theory of Gravity
arXiv:0801.0905 · doi:10.1088/1475-7516/2008/10/010
Abstract
The torsion is shown to be vitally important in the explanation of the evolution of the universe in a large class of gravitational theories containing quadratic terms of curvature and torsion. The cosmological solutions with homogeneous and isotropic torsion in a model of de Sitter gauge theory of gravity are presented, which may explain the observation data for SN Ia when parameters are suitably chosen and supply a natural transit from decelerating expansion to accelerating expansion without the help of the introduction of other strange fields in the theory.
