Abstract

In this paper, the authors discuss oscillation, nonoscillation and growth of solutions of the generalized nonlinear difference equation$$\label{6.15.1}\Delta_\ell(p(k)\Delta_\ell u(k))+f(k)F(k,u(k),\Delta_\ell u(k))=g(k,u(k),\Delta_\ell u(k)),$$ $$k\in[a,\infty)$$, where the functions $$p$$, $$f$$, $$F$$ and $$g$$ are defined in their domain of definition and $$\ell$$ is a positive real. Further, $$p(k)>0$$ for all $$k\in[a,\infty)$$ for some $$a\in[0,\infty)$$ and for all $$j=k-a-\Big[\frac{k-a}{\ell}\Big]\ell,R_{a+j,k}\to\infty$$, where $R_{t+j,k}=\sum\limits_{r=0}^{\frac{k-\ell-t-j}{\ell}}\frac{1}{p(t+j+r\ell)},\quad t\in [a,\infty)\text{ and } k\in\mathbb{N}_\ell(t+j+\ell).$
