Oscillation and comparison theorems for half-linear second-order difference equations. (English) Zbl 0983.39006
Authors’ abstract: The authors consider second-order difference equations of the type $$\Delta\bigl((\Delta y_n)^\alpha \bigr)+ q_ny^\alpha_{ \sigma (n)}=0, \tag E$$ where $\alpha>0$ is the ratio of odd positive integers, $\{q_n\}$ is a positive sequence, and $\{\sigma(n)\}$ is a positive increasing sequence of integers with $\sigma(n) \to\infty$ as $n\to\infty$. They give some oscillation and comparison results for equation (E).
