What is K-Essence and Tachyons in Brane-Worlds about?

This document discusses cosmological models with k-essence and extended tachyons on a 3-dimensional brane. It finds: 1) For a k-field evolving linearly with time, the scale factor has power-law behavior and the potential is inversely proportional to time. 2) For an "atypical" k-essence model, the potential is inversely proportional to the k-field, generalizing the inverse-square potential of standard cosmology. 3) Introducing extended tachyon fields, including phantom tachyons, leads to expanding, cont
