Abstract
The basic cosmological equations of the scalar-tetradic theory A were recently obtained. Here, the general matter-dominated solution of these equations (which involve the arbitrary dimensionless constantsD andW) is derived and studied in the caseD=0. One of the cosmological models obtained in this way appears to be free of singularities (W<0) whereas another singular model (W>8/3) becomes compatible with small energy densities (10−31 gcm−3). More study about the caseD#0, as well as about other equations of state and other scalar-tetradic theories, could lead to new interesting results.
