Abstract

In this note we review some of the latest research on the qualitative analysis of solutions of difference equations using fixed point theory and Lyapunov functionals. It turns out that the use of fixed point theory alleviates some of the difficulties that arise from the use of Lyapunov functionals. Using fixed point theory requires us to find a mapping from suitable spaces that is a solution of the given difference equation. Once the suitable mapping is constructed there will be many fixed pint theorems to use, depending on the given equation, that yield a fixed point of that mapping and satisfies our initial value problem. In some cases a regular contraction argument will not be suitable and hence we replace it with what we call Large Contraction.
