Effects of anisotropy and spatial curvature on the pre-big bang scenario

  title={Effects of anisotropy and spatial curvature on the pre-big bang scenario},
  author={Dominic Clancy and James E. Lidsey and Reza Tavakol},
A class of exact, anisotropic cosmological solutions to the vacuum Brans– Dicke theory of gravity is considered within the context of the pre–big bang scenario. Included in this class are the Bianchi type III, V and VIh models and the spatially isotropic, negatively curved Friedmann–Robertson–Walker universe. The effects of large anisotropy and spatial curvature are determined. In contrast to negatively curved Friedmann–Robertson–Walker model, there exist regions of the parameter space in which… CONTINUE READING
