We are now able to obtain the full system of equations the govern the background expansion in this model:
\begin{align}
& E^2(z) = g(z)[\Omega_m(z) +
\Omega_\Lambda(z)],\\ \Omega_\Lambda(z)], \label{syshubble}\\
& (\Omega_m + \Omega_\Lambda) dg + g d \Omega_\Lambda = 0,
\label{sysomol} \\
& \Omega_\Lambda(z) = \Omega_\Lambda^0 + \nu [E^2(z) - 1],
\label{syslambda} \\
& \Omega_m(z) = \Omega_m^0 (1+z)^{3(1+w_n)},
\end{align}
The first equation is the equivalent of the Friedmann equation in the $\Lambda CDM$ model, the second is the diffrerential form of the Bianchi equation \ref{bianchiconstraint}, the third is just e rewrite of \ref{secondlambdalaw} using the density parameter and the last equation is a rewrite of the standard equation for $\rho_m$ generalized to include relativistic ($w_m = \frac{1}{3}$) and nonrelativistic matter ($w_m = 0$).
