Analysis of a predator-prey model with modified Leslie-Gower and Holling-type II schemes with stochastic perturbation
TL;DR: In this paper, a predator-prey model with modified Leslie-Gower and Holling-type II schemes with stochastic perturbation is considered, and a unique positive solution to the system with positive initial value is given and persistent condition is established.
Journal ArticleDOI
The threshold of a stochastic SIS epidemic model with vaccination
TL;DR: There is a threshold of the stochastic model which determines the outcome of the disease in case the white noises are small, and sufficient conditions for extinction and persistence in mean are obtained.
Journal ArticleDOI
Multiple positive solutions for the boundary value problem of a nonlinear fractional differential equation
TL;DR: In this paper, the authors considered the properties of Green's function for the nonlinear fractional differential equation boundary value problem D 0 + α u( t ) = f ( t, u ( t ) ), 0 t 1, u ( 0 ) = u ( 1 ) = 0, where 3 α ≤ 4 is a real number, and D 0+α is the standard Riemann-Liouville differentiation.
Journal ArticleDOI
Global stability and stochastic permanence of a non-autonomous logistic equation with random perturbation☆
TL;DR: In this paper, Jiang et al. presented a randomized non-autonomous logistic equation with random perturbation, where B ( t ) is a 1-dimensional standard Brownian motion.
Journal ArticleDOI
The ergodicity and extinction of stochastically perturbed SIR and SEIR epidemic models with saturated incidence
TL;DR: In this paper, a stochastic perturbation into SIR and SEIR epidemic models with saturated incidence was investigated and the long time behavior of the two systems was studied, and it was shown that under some conditions, the solution has the ergodic property as R 0 > 1, while exponential stability asR 0 ⩽ 1.
