10-dimensional cosmology with Gauss-Bonnet gravity in generalized scalar-tensor theories from superstring theories

Abstract

Superstring theories are promising candidates for unifying gravity with all matter interactions. In this work, we discussed a particular 10-dimensional cosmology based on Gauss-Bonnet invariant term coupled to a generalized scalar-tensor theory as resulting from superstring theories. Some interesting features concerning the late-time dynamics are explored and described in some details.
