K-essence and tachyons in braneworld cosmology
We investigate a k-essence field localized on the brane evolving linearly with the cosmological time for some kinetic functions and consider the atypical k-essence model for linear and nonlinear k-fields in FriedmannRobertsonWalker (FRW) cosmology. In the former case the k-field is driven by an inve...
