The long time behavior of a predator–prey model with disease in the prey by stochastic perturbation

摘要

In this paper, we formulate a predator–prey model with disease in the prey by stochastic perturbation. Using Lyapunov analysis methods we discuss the asymptotic behavior of this solution. Furthermore, we investigate whether that there exists a stationary distribution for this system and if it has the ergodic property. Finally we make simulations to illustrate our analytical results.
