Stability analysis of delayed SIR epidemic models with a class of nonlinear incidence rates
(2012-12-31)
We analyze stability of equilibria for a delayed SIR epidemic model, in which population growth is subject to logistic growth in absence of disease, with a nonlinear incidence rate satisfying suitable monotonicity conditions. ...
Lyapunov functional techniques for the global stability analysis of a delayed SIRS epidemic model
(2012-12-31)
In this paper, we study the global dynamics of a delayed SIRS epidemic model for transmission of disease with a class of nonlinear incidence rates of the form βS(t)∫ 0 hf(τ)G(I(t-τ))dτ. Applying Lyapunov functional techniques ...
Global stability of sirs epidemic models with a class of nonlinear incidence rates and distributed delays
(2012-12-31)
In this article, we establish the global asymptotic stability of a disease-free equilibrium and an endemic equilibrium of an SIRS epidemic model with a class of nonlinear incidence rates and distributed delays. By using ...
Stability analysis of multi-compartment models for cell production systems
(2012-12-31)
We study two-and three-compartment models of a hierarchical cell production system with cell division regulated by the level of mature cells. We investigate the structure of equilibria with respect to parameters as well ...
Two types of condition for the global stability of delayed sis epidemic models with nonlinear birth rate and disease induced death rate
(2012-12-31)
We study global asymptotic stability for an SIS epidemic model with maturation delay proposed by K. Cooke, P. van den Driessche and X. Zou, Interaction of maturation delay and nonlinear birth in population and epidemic ...
Global dynamics of a delayed SIRS epidemic model with a wide class of nonlinear incidence rates
(2012-12-31)
In this paper, by constructing Lyapunov functionals, we consider the global dynamics of an SIRS epidemic model with a wide class of nonlinear incidence rates and distributed delays ∫ h 0 p(τ)f(S(t),I(t- τ))dτ under the ...
Global stability for a discrete epidemic model for disease with immunity and latency spreading in a heterogeneous host population
(2012-12-31)
In this paper, we propose a discrete epidemic model for disease with immunity and latency spreading in a heterogeneous host population, which is derived from the continuous case by using the well-known backward Euler method ...
Global stability for a discrete SIS epidemic model with immigration of infectives
(2012-12-31)
In this paper, we propose a discrete-time SIS epidemic model which is derived from continuous-time SIS epidemic models with immigration of infectives by the backward Euler method. For the discretized model, by applying new ...
Global dynamics of difference equations for SIR epidemic models with a class of nonlinear incidence rates
(2012-12-31)
In this paper, by applying a variation of the backward Euler method, we propose a discrete-time SIR epidemic model whose discretization scheme preserves the global asymptotic stability of equilibria for a class of corresponding ...
On a generalization of the global attractivity for a periodically forced Pielou's equation
(2012-12-31)
In this paper, we study the global attractivity for a class of periodic difference equation with delay which has a generalized form of Pielou's difference equation. The global dynamics of the equation is characterized by ...
