Oscillating Universe from inhomogeneous EoS and coupled dark energy
  An occurrence of an oscillating Universe is showed using an inhomogeneous
equation of state for dark energy fluid. The Hubble parameter described
presents a periodic behavior such that early and late time acceleration are
unified under the same mechanism. Also, it is considered a coupling between
dark energy fluid, with homogeneous and constant EoS, and matter, that gives a
periodic Universe too. The possible phantom phases and future singularities are
studied in the oscillating Universe under discussion. The equivalent
scalar-tensor representation for the same oscillating Universe is presented
too.
