Bifurcations and dynamic complexity in simple ecological models. 114464 the existence and local stability of the disease-free equilibrium and endemic equilibrium of the model are discussed.
Xu Chen 1 and Lei Zhang 2. Berryman and Millstein [ 3 ] investigated an SVEIS epidemic leei for an infectious disease that spreads in the host population through horizontal transmission, and they have shown that the model exhibits two equilibria, namely, the disease-free equilibrium and the endemic equilibrium.

Well-posedness lri dynamics of the stochastic fractional magneto-hydrodynamic equations. It is found that the flow can be classified as six stages, including a bi-linear flow regime, a linear flow regime, a transition flow regime, an inter-porosity flow regime from the matrix to the fractures in the inner region, inter-porosity flow regime from matrix to fractures in the outer region, and a boundary dominant flow regime.
By a simple calculation, Conditions A in Theorem 2 can be written in the following form:. The authors would like to thank anonymous referees for their constructive comments which improve the readability of the paper.
