Abstract

What is the asymptotic future of a scalar-field model if the assumption of isotropy is relaxed in generic, homogeneous space-times with general relativity? This paper is a continuation of our previous work on Bianchi cosmologies with a pp-form field (where p{1,3}p\,\in\,\{1,3\})---or equivalently: an inhomogeneous, mass-less scalar gauge field with a homogeneous gradient. In this work we investigate such matter sector in General Relativity, and restrict to space-times of the particular Bianchi types VI0_0 and VIh~_{\tilde{h}}, where h~=h<01/91\tilde{h}=h<0\,\cap\,\neq\,-1/9\,\cup\,-1. We show that the previously found fabric of exact solutions named Wonderland are future attractors in B\mathcal{B}(VI0_0) and B\mathcal{B}(VIh~_{\tilde{h}}), extending the Collins perfect-fluid equilibrium set to include a pp-form (with p{1,3}p\,\in\,\{1,3\}). We also write down the line-element corresponding to Wonderland in VIh~_{\tilde{h}} and give explicit expressions for the underling gauge-potential ϕ(t,x)\phi(t,\mathbf{x}) corresponding to this solution. Simulation of a path approaching Wonderland in Bianchi type I is also given.
