The rest of this paper is organized as follows. Characterizations of common fixed points of one-parameter nonexpansive semigroups. Methods of Qualitative Theory in Nonlinear Dynamics. A free boundary problem for lel ratio-dependent diffusion predator-prey system.
Acknowledgements The authors would like to thank anonymous referees for their constructive comments which improve the readability of the paper.
How does Europe PMC derive its citations network? However, for an endemic disease, we should incorporate the demographic structure into the epidemic model. In addition, a precise description of secondary fractures in SRV regions is of critical importance for production analysis and prediction.
Introduction The role of mathematical modeling has been intensively growing in the study of epidemiology. InYan et al. In this paper, we will study the existence of the disease-free equilibrium and endemic equilibrium, and the stability of the disease-free equilibrium and the endemic equilibrium for this system. Genealogy with seasonality, the basic reproduction number, and the influenza pandemic.

Conditions will be derived for the existence of a flip bifurcation and a Hopf bifurcation by using bifurcation theory [ 1112 ] and the center manifold theorem [ 13 ].
Many authors have investigated the autonomous epidemic models.
Journal of Inequalities and Applications. Energy Innovation Software Co. Wan L, Xu R. I dr tkmw skis tiyamlio. Guckenheimer and Holmes [ 2 ] examined an SIR epidemic model with a non-monotonic incidence rate, and they also analyzed the dynamical behavior of the model and derived the stability conditions for the disease-free and the endemic equilibrium.

It should leii emphasized that system 1 has no vital dynamics births and deaths because it was usually used to describe the transmission dynamics of a disease within a short outbreak period.
