Cold Dark Matter and Holographic Dark Energy Cosmological Model with Big rip singularity

We have explored cold dark matter and holographic dark energy cosmological models with big rip singularity. To obtain the solution of the field equation, we have supposed that scalar expansion $\theta$ is proportional to shear scalar $\sigma ^2$ which leads to $p_1=(p_2) ^n$, where $A_1$, $A_2$ are metric potentials and $n$ is constant. Big bang and Big rip singularity are investigated and analyzed the state-finder parameter. The physical and geometrical parameters of the universe are explained.
