Perturbation in an interacting dark universe
  In this paper we have considered an interacting model of dark energy and have
looked into the evolution of the dark sectors. By solving the perturbation
equations numerically, we have studied the imprints on the growth of matter as
well as dark energy fluctuations. It has been found that for higher rate of
interaction strength for the coupling term, visible imprints on the dark energy
density fluctuations are observed at the early epochs of evolution.
