Exact solutions of the field equations are obtained by assuming (i) a negative constant value of the deceleration parameter, (ii) the component sigma(1)(1) of the shear tensor sigma(i)(j) is proportional to the mean Hubble parameter, and (iii) the gauge function phi is proportional to a power function of the average scale factor. We have also discussed some important physical aspects of the model, which is in agreement with the modern cosmological observations. 收起
