| Abstract: | The aim of this paper is to present sufficient conditions for all unbounded solutions of the second order advanced differential equations of the neutral type(1) to be oscillatory.Some new sufficient conditions are also derived for the convergence of nonoscillatory solutions of(1) to zero. |
| |
| Keywords: | advanced equation of neutral type oscillation criterion nonoscillatory solutions |
