Rolling Tachyon in Nonlocal Cosmology
arXiv:0710.0404 · doi:10.1063/1.2823793
Abstract
Nonlocal cosmological models derived from String Field Theory are considered. A new method for constructing rolling tachyon solutions in the FRW metric in two field configuration is proposed and solutions of the Friedman equations with nonlocal operator are presented. The cosmological properties of these solutions are discussed.
