O článku:
In this paper, we study the oscillatory behavior of solutions of the fractional difference equation of the form \begin{eqnarray*} \Delta\Bl(r(t)g\bl(\Delta^{\alpha}x(t)\br)\Br) +p(t)f \bgl(\sum_{s=t_{0}}^{t-1+\alpha}(t-s-1)^{(-\alpha)}x(s) \bgr) = 0, \qquad t\in \mathbb{N}_{t_{0}+1-\alpha}, \end{eqnarray*} where $\Delta^\alpha$ denotes the Riemann-Liouville fractional difference operator of order $\alpha,$ $ 0 < \alpha \leq 1$, $\mathbb{N}_{t_0+1-\alpha}=\{t_0+1-\alpha,t_0+2-\alpha,\dots\}$, $t_0 > 0$ and $\ \gamma > 0$ is a quotient of odd positive integers. We establish some oscillatory criteria for the above equation, using the Riccati transformation and Hardy type inequalities. Examples are provided to illustrate the theoretical results.
