Anisotropic and Curved String Cosmologies

Part of the Astrophysics and Space Science Library book series (ASSL, volume 291)


Let us extend the work of the last Chapter to cosmologies containing spatial curvature terms [51]. This will enable us, via a qualitative analysis, to determine (among other things) whether models evolve from a low-curvature regime and thereby test the self-consistency of the low-energy effective string cosmology paradigm. In particular, we consider the class of “isotropic curvature” models [265, 314] , which are spatially homogeneous but contain non-trivial curvature and anisotropy and are characterized by the fact that the 3-dimensional Ricci curvature tensor is isotropic; i.e., (3) Rij is proportional to ij on the spatial hypersurfaces and these surfaces therefore have constant curvature k [265].
