A blow up condition for a nonautonomous semilinear system

Electronic Journal of Differential Equations, 2006
We give a sufficient condition for finite time blow up of the nonnegative mild solution to a nonautonomous weakly coupled system with fractal diffusion having a time dependent factor which is continuous and nonnegative.

Periodic Orbits for a Three-Dimensional Biological Differential Systems

Abstract and Applied Analysis, 2013
We study the existence of periodic orbit for a differential system describing the effects of indirect predation over two preys. Besides discussing a generalized version of the model, we present some remarks and numerical experiments for the nonautonomous

Existence of periodic solutions for subquadratic discrete system involving the p-Laplacian

Electronic Journal of Differential Equations, 2017
An existence theorem on periodic solution is established for a class of nonautonomous discrete system involving the p-Laplacian under a subquadratic growth condition. The conclusion is based on saddle point theorem and variational methods.

Periodic solutions of multispecies-competition predator-prey system with Holling's type III functional response and prey supplement

Electronic Journal of Differential Equations, 2007
In this paper, we consider a nonautonomous multispecies competition predator-prey system with Holling's type III functional response and prey supplement. It is proved that the system is uniformly persistent under some conditions. Furthermore, we show

The Shrinking Target Problem for Nonautonomous Dynamical Systems Corresponding to Cantor Series Expansion over Formal Laurent Series

Mathematics
In this paper, we study the shrinking target problem regarding Q-Cantor series expansions of the formal Laurent series field. We provide the Hausdorff dimension of a very general shrinking target scheme generated by the nonautonomous dynamical system on ...

Positive periodic solutions for nonautonomous impulsive neutral functional differential systems with time-varying delays on time scales

Electronic Journal of Differential Equations, 2010
Using a fixed point theorem of strict-set-contraction, we prove the existence of positive periodic solutions for a class of nonautonomous impulsive neutral functional differential system with time-varying delays on time scales.
