Sunto
Si studia l’equazione non omogenea del secondo ordine alle differenze, \begin{equation}\label{*}\Delta (r_{n}\Delta u_{n}) + a_{n}f(u_{n}) = b_{n}\end{equation} nel suo comportamento asintotico. Fra l’altro, si danno condizioni sufficienti per il tendere allo zero di tutte le soluzioni di (*) non oscillatorie.
