Abstract: The discovery that the Universe is undergoing an accelerated expansion hassuggested the existence of an evolving equation of state. This paper discussesvarious wormhole solutions in a spherically symmetric spacetime with anequation of state that is both space and time dependent. The solutions obtainedare exact and generalize earlier results on static wormholes supported byphantom energy.
