The Universe With Bulk Viscosity | Arbab I. Arbab
; | Date: |
20 Dec 1998 | Journal: | Chin.J.Astron.Astrophys. 3 (2003) 113 | Subject: | gr-qc | Abstract: | Exact solutions for a model with variable $G$, $Lambda$ and bulk viscosity are obtained. Inflationary solutions with constant (de Sitter-type) and variable energy density are found. An expanding anisotropic universe is found to isotropize during its course of expansion but a static universe is not. The gravitational constant is found to increase with time and the cosmological constant decreases with time as $Lambda propto t^{-2}$. | Source: | arXiv, gr-qc/9812070 | Services: | Forum | Review | PDF | Favorites |
