22 Apr 2002 | | Journal: | Class.Quant.Grav. 19 (2002) 4923-4932 | | Subject: | gr-qc hep-th | | Abstract: | We investigate the dynamics of a Bianchi I brane Universe in the presence of a nonlocal anisotropic stress ${cal P}_{mu
u}$ proportional to a "dark energy" ${cal U}$. Using this ansatz for the case ${cal U} > 0$ we prove that if a matter on a brane satisfies the equation of state $p=(gamma-1)
ho$ with $gamma le 4/3$ then all such models isotropize. For $gamma > 4/3$ anisotropic future asymptotic states are found. We also describe the past asymptotic regimes for this model. | | Source: | arXiv, gr-qc/0204071 | | Services: | Forum | Review | PDF | Favorites | |
