Large Dynamical System Analysis for Anisotropic Universe in Brans-Dicke Theory (1112.5930v1)
Published 27 Dec 2011 in physics.gen-ph
Abstract: In this work, we have studied the Brans-Dicke (BD) cosmology in anisotropic models. We present three dimensional dynamical system describing the evolution of anisotropic models containing perfect fluid and BD scalar field with self-interacting potential. The relevant equations have been transformed into the dynamical system. The critical points and the corresponding eigen values have been found in radiation, dust, dark energy, $\Lambda$CDM and phantom phases of the universe. The natures and the stability around the critical points have also been investigated.
