主 题:SIR epidemic model white noise Levy noise stationary distribution persistence extinction
摘 要:Environmental perturbations are unavoidable in the propagation of infectious *** this paper,we introduce the stochasticity into the susceptible-infected recovered(SIR)model via thc^parameter perturbation *** stochastic disturbances associated with the disease transmission coefficient and the mortality rate are presented with two perturbations:Gaussian white noise and Levy jumps,*** idea provides an overview of disease dynamics under different random perturbation *** using new techniques and methods,we study certain interesting asymptotic properties of our perturbed model,namely:persistence in the mean,ergodicity and extinction of the *** illustrative purposes,numerical examples are presented for checking the theoretical study.
