Dynamics of tachyon field in spatially curved FRW universe
arXiv:1003.1870 · doi:10.1016/j.physletb.2010.02.071
Abstract
The dynamics of a tachyon field plus a barotropic fluid is investigated in spatially curved FRW universe. We perform a phase-plane analysis and obtain scaling solutions accompanying with a discussion on their stability. Furthermore, we construct the form of scalar potential which may give rise to stable solutions for spatially open and closed universe separately.
