Query: Phases of the Brans-Dicke Cosmology with Matter   We study the cosmology of the Brans-Dicke theory with perfect fluid type
matter. In our previous work, we found exact solutions for any Brans-Dicke
parameter $\omega$ and for general parameter $\gamma$ of equation of state. In
this paper we further study the cosmology of these solutions by analyzing them
according to their asymptotic behaviors. The cosmology is classified into 19
phases according to the values of $\gamma$ and $\omega$. The effect of the
cosmological constant to the Brans-Dicke theory is a particular case of our
model. We give plot of time evolution of the scale factor by numerical
investigations. We also give a comparison of the solutions for the theories
with and without matter.
