Abstract
In common discussions, the cosmological constant is identified with vacuum energy. The idea here is to identify it with the Lorentz-invariant scalar a risen by the contraction of the stress-energy tenser of ordinary matter whi ch represents a form of the quintessence. We describe a quintessence cosmol ogical scenario within the Friedmann universe and confront it with data. (C ) 2001 Elsevier Science B.V. All rights reserved.
