Growth index and statefinder diagnostic of Oscillating Dark Energy
  We study is some detail the Cosmology of Oscillating Dark Energy described by
concrete equations-of-state investigated recently in the literature. In
particular, at the background level we compute the statefinder parameters,
while at the level of linear cosmological perturbations we compute the growth
index $\gamma$ as well as the combination parameter $A=f \sigma_8$. The
comparison with $\Lambda$CDM is made as well.
