| Abstract: | In this paper, we deal with oscillatory and asymptotic properties of solutions of a fourth order sub-linear differential equation with the oscillatory operator. We establish conditions for the nonexistence of positive and bounded solutions and an oscillation criterion. |
| Keywords: | Fourth order nonlinear differential equation Oscillation Positive bounded solution Positive unbounded solution |
