摘要
We study a model in which a closed universe with dust and quintessence matter components may look like an accelerated flat Friedmann-Robertson-Walker (FRW) universe at low redshifts. Several quantities relevant to the model are expressed in terms of observed density parameters, Omega(M) and Omega(Lambda), and of the associated density parameter Omega(Q) related to the quintessence scalar field Q.
