On the behavior of the solutions to autonomous linear difference equations with continuous variable
Autonomous linear neutral delay and, especially, (non-neutral) delay difference equations with continuous variable are considered, and some new results on the behavior of the solutions are established. The results are obtained by the use of appropriate positive roots of the corresponding characteristic equation.
On the behaviour of the solutions of a -order cyclic-type system of max difference equations
We investigate the behaviour of the solutions of a -dimensional cyclic system of difference equations with maximum. More precisely, we study the existence and the number of the equilibria in the case when is an odd or an even positive integer, but also for the various values of the exponents of the terms of the difference equations of this system. In addition, we find invariant intervals for our system and we invistegate the convergence of the solutions to the unique positive equilibrium. Finally,...
