Quintessence inhomogeneous cosmology
Luis P. Chimento, Alejandro S. Jakubi, Diego Pavon
Abstract
The Einstein-Klein-Gordon field equations are solved in a inhomogeneous shear-free universe containing a material fluid, a self-interacting scalar field, a variable cosmological term, and a heat flux. A quintessence-dominated scenario arises with a power-law accelerated expansion compatible with the currently observed homogeneous universe.
