Stiff Fluid in Accelerated Universes with Torsion [PDF]
Journal of Gravity, 2013 The flat Friedmann universes filled by stiff fluid and a nonminimally coupled material scalar field with polynomial potentials of the fourth degree are considered in the framework of the Einstein-Cartan theory. Exact general solution is obtained for arbitrary positive values of the coupling constant .
