Adiabatic Particle Production with Decaying $\mathrm{\Lambda }$ and Anisotropic Universe

Here we study an anisotropic model of the universe with constant energy per particle. A decaying cosmological constant and particle production in an adiabatic process are considered as the sources for the entropy. The statefinder parameters $\{r,s\}$ are defined and their behaviour are analyzed graphically in some cases.
