Abstract

The system comprises of a commensal (S₁) common to two hosts S₂ and S₃ with mortality rate for the host (S₃). Here all the three species posses limited resources. The model equations constitute a set of three first order non-linear simultaneous coupled differential equations. Criteria for the asymptotic stability of all the eight equilibrium states are established. Trajectories of the perturbations over the equilibrium states are illustrated. Further the global stability of the system is established with the aid of suitably constructed Liapunov’s function and the numerical solutions for the growth rate equations are computed using Runge-Kutta fourth order scheme.
