Periodic solutions for a coupled pair of delay difference equations

Periodic Solutions for a Coupled Pair of Delay Difference Equations

has been studied by many authors, see, for example, [1, 3, 5, 7, 8, 9] and the references contained therein. The above equation may be regarded as a mathematical model for a number of dynamical processes. In particular, xn may represent the size of a population in the time period n. Since it is possible that the population may be influenced by another factor of the form −ĥn f2(n,xn−τ(n)), we ar...

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.
