Abstract

We consider issues related to tachyonic inflation with inverse-power-law potential. We find the solution of the evolution equations in the slow-roll limit in FRW as well as in the brane cosmology. Using the holographic entropy bound, we estimate the quantum-gravitational discreteness of tachyonic inflation perturbations.
