Oscillating phantom in $F(R)$ gravity
arXiv:0909.1249 · doi:10.1143/PTP.122.1267
Abstract
We investigate the oscillating effective equation of state (EoS) of the universe around the phantom divide in the framework of $F(R)$ gravity. We illustrate the behavior of $F(R)$ with realizing multiple crossings of the phantom divide.
