Persistence and Periodic Solution on a Nonautonomous SIS Model with Delays
time delay liapunov functional persistence
2007/12/11
An SIS model with periodic maximum infectious force, recruitment rate and the removal rate of the infectives has been investigated in this article. Sufficient conditions for the permanence and extinct...

diffusive food chain system positive periodic solution
2007/12/11
By using the continuation theorem of coincidence degree theory, the existence of a positive periodic solution for a nonautonomous diffusive food chain system of three species. { dx_1(t)/dt = x_1(t)[r_...
THE EXTINCTION IN NONAUTONOMOUS PREY-PREDATORLOTKA-VOLTERRA SYSTEMS
Nonautonomous Lotka-Volterra
2007/12/11
In this paper some new criteria about the extinction of solutions for two dimensional nonautonomous prey-predator Lotka-Volterra systems are established. The criteria obtained improve the results by G...
Permanence in Nonautonomous Predator-prey Lotka-Voterra Systems
nonautonomous lotka-volterra system
2007/12/10
In this paper some easily verifiable sufficient conditions on the permanence of solutions for general nonautonomous two-species predator-prey model are established. These new criteria improve and exte...
