On the periodic nature of some max-type difference equations
International Journal of Mathematics and Mathematical Sciences, 2005 We study some qualitative behavior of solutions of some max-type difference equations with periodic coefficients. Some new results of the periodicity character of solutions of that type of difference equations will be established.

solutions of period three for a non-linear difference equation [PDF]
The Journal of the Australian Mathematical Society. Series B. Applied Mathematics, 1984 AbstractThe paper uses the factorisation method to discuss solutions of period three for the difference equationwhich has been proposed as a simple mathematical model for the effect of frequency dependent selection in genetics. Numerical values are obtained for the critical values of a at which solutions of period three first appear.

Linear difference equations, frieze patterns, and the combinatorial Gale transform
Forum of Mathematics, Sigma, 2014 We study the space of linear difference equations with periodic coefficients and (anti)periodic solutions. We show that this space is isomorphic to the space of tame frieze patterns and closely related to the moduli space of configurations of points in ...

Periodic solutions of neutral difference equations
Computers & Mathematics with Applications, 2003 The authors consider ``neutral'' difference equations \[ \triangle(D(n,x_n))=f(n,x_n) \] with finite and infinite delays. Here \(D\) and \(f\) are defined on some subsets of \({\mathbb Z}\times C \rightarrow {\mathbb R}^k\), \(x_n=x(n+s)\) where both \(n\) and \(s\) are integers, \(-r\leq s\leq 0\) and \(C\) is the space of finite \({\mathbb R}^k ...

The Periodic Solutions of Nonlinear Differential Difference Equations
Journal of Mathematical Analysis and Applications, 1994 The existence of slowly oscillating periodic solutions and rapidly oscillating solutions to a class of differential difference equations is considered. Sufficient conditions under which the equations have at least \(N\) or an infinite number of nonconstant periodic solutions are established. For example, it is shown that if \(ah > {\pi \over 2}\), then
