Uniform persistence for a predator–prey system with delays

Applied Mathematics and Computation, 2006
This paper deals with the uniform persistence and the existence of positive periodic solutions in a delayed predator-prey model with Holling-type-III functional response. An example is included to illustrate the importance of the main result.

Uniform persistence for a discrete predator–prey system with delays

Applied Mathematics and Computation, 2011
The authors deal with a discrete predator-prey model with monotonic functional responses and give a sufficient condition of uniform persistence for the system.

Uniform persistence and net functions

Journal of Dynamics and Differential Equations, 1995
The authors discuss uniform persistence for retarded functional differential equations. For such equations, the phase space consists of some functions from \((- \infty, 0]\) into its range space \(X\). The approach developed in this paper, which is natural and useful, is to construct a set of Lyapunov functions \(\{V_1,\dots, V_p\}\) which are defined ...

Uniform persistence and periodic solutions for Kolmogorov system with delays

Nonlinear Analysis: Real World Applications, 2009
This short paper establishes some sufficient technical conditions that assure uniform persistence of solutions to a class of nonautonomous delayed differential systems of Kolmogorov type. To illustrate the obtained result, the paper presents some direct applications to delayed predator-prey models.
