摘要：

The mounting evidence that the universe is presently undergoing accelerating expansion has restored some credit to the scenarios with a nonvanishing cosmological constant. From the point of view of a theory of fundamental interactions, one may argue that a dynamical component with negative pressure is easier to achieve. As an illustration, the quintessence scenario is described and its shortcomings are discussed in connection with the nagging "cosmological constant problem.".
