K-essential Phantom Energy: Doomsday around the Corner? Revisited
Abstract
Description
We generalize some of those results reported by González-Díaz by further tuning the parameter ($β$) which is closely related to the canonical kinetic term in $k$-essence formalism. The scale factor $a(t)$ could be negative and decreasing within a specific range of $β$ ($\equiv -1/ω$, $ω$ : the equation-of-state parameter) during the initial evolutional period.
