We investigate the possibility that the matter of the Universe has a significant component (the quintessence component) determined by the equation of state (Formula presented) with (Formula presented) Here, we find conditions under which a closed model may look similar to a flat Friedmann-Robertson-Walker universe at low redshift. We study this problem in Einstein’s general relativity and Brans-Dicke theories. In both cases we obtain explicit expressions for the quintessence scalar potential (Formula presented) and the angular size as a function of the redshift.
