deterministic model of corruption dynamics in nigeria via homotopy perturbation method

Corruption is a slowly decaying poison in nigeria. corruption is a global problem that individuals in a community can be exposed to. this paper developed the dynamics of corruption and the compartments were divided into six sections: susceptible, exposed, corrupt, honest, punished and recovered. the paper was designed to deal with the stability of corrupt individuals and, using the homotopy perturbation technique, the model equations are solved for simulations to performed numerically. the analysis findings demonstrate that the corruption-free equilibrium is locally asymptotically stable if r0<1, indicating that there is corruption in the population. disappears and if r0>1, means that the number of corruption rises per-capital in a society. also from the results, the homotopy perturbation method shows accuracy and convergence very quickly for numerical simulations despite it require perturbation for convergent. the observations and suggestions are outlined to have a corruption-free society.
