Abstract
We consider a FRW cosmological model with an exotic fluid known as Chaplygi n gas. We show that the resulting evolution of the universe is not in disag reement with the current observation of cosmic acceleration. The model pred ict an increasing value for the effective cosmological constant. (C) 2001 E lsevier Science B.V. All rights reserved.
