Study of a Bianchi type-V cosmological model with torsion

· Phys. Rev. D; (United States)
A Bianchi type-V exact solution of the Einstein-Cartan theory representing several classes of perfect-fluid homogeneous cosmological models is studied. With the introduction of an effective energy-momentum tensor, a dual description of the solution is given within the framework of general relativity, whereby it is shown that the two theories, although formally equivalent, provide physically inequivalent interpretations of the solution. Examined in some detail are the singularity behavior as well as other features of the models.
