Positive Periodic Solutions of N-Species Neutral Delay Systems

Positive Periodic Solutions in Neutral Delay Difference Equations

We use Krasnoselskii’s fixed point theorem to obtain sufficient conditions for the existence of a positive periodic solution of the neutral delay difference equation x(n+ 1) = a(n)x(n) + c∆x(n− τ) + g(n, x(n− τ)). AMS Subject Classifications: 39A10, 39A12.

Positive periodic solutions for neutral multi-delay logarithmic population model

* Correspondence: csutmlang@163. com School of Mathematical Science and Computing Technology, Central South University, Changsha, 410083, China Abstract Based on an abstract continuous theorem of k-set contractive operator and some analysis skill, a new result is obtained for the existence of positive periodic solutions to a neutral multi-delay logarithmic population model. Some sufficient cond...
