  In the next step we focus briefly o n the cosmological dynamics of a bulk scalar field in the RS II braneworld scenario (see Refs. [48, 49, 66] for details) to see the relation b etween bulk.

Coley (Submitted on 4 Oct , last revised 25 Apr (this version, v2)) Abstract: We show that generically the initial singularity is isotropic in spatially homogeneous cosmological models in the brane-world scenario. We then argue that it is plausible that the initial Cited by: @article{osti_, title = {Cosmological tachyon condensation}, author = {Bilic, Neven and Tupper, Gary B and Viollier, Raoul D and Centre of Theoretical Physics and Astrophysics, University of Cape Town, Rondebosch }, abstractNote = {We consider the prospects for dark matter/energy unification in k-essence type cosmologies..

String theory is a broad and varied subject that attempts to address a number of deep questions of fundamental physics. String theory has been applied to a variety of problems in black hole physics, early universe cosmology, nuclear physics, and condensed matter physics, and it has stimulated a number of major developments in pure mathematics.   We review recent developments and results in testing general relativity (GR) at cosmological scales. The subject has witnessed rapid growth during the last two decades with the aim of addressing the question of cosmic acceleration and the dark energy associated with it. However, with the advent of precision cosmology, it has also become a well-motivated endeavor by itself to test Cited by: We review some general aspects of braneworld cosmologies in which an inflationary period driven by a scalar field confined on the brane is described by a nonstandard effective Friedmann equation.
