摘要：
Cosmological scalar fields with negative pressure and a time-varying, spatially fluctuating energy density -quintessence- have recently obtained wide support from different observations and theoretical considerations. We present here an overview of the cosmological evolution of scalar fields with arbitrary potentials, in the presence of a barotropic fluid, and their influence on the universe expansion.
