Consider the nonlinear neutral delay differential equation with P(t), Q ( t ) continuous, T > 0, a 2 0. We obtain new suflicient conditions for the oscillation of all solutions by an associate linear equation, and thereby establish some new criteria as proposed in an earlier open problem. ') Resea

This note is concerned with the oscillatory behavior of a linear differentialdifference system of neutral type. Criteria for oscillations are obtained for autonomous and nonautonomous systems.
In this paper, effective sufficient conditions for the oscillation of all solutions of impulsive neutral delay differential equations of the form are established. Our results reveal the fact that the oscillatory properties of all solutions of Eqs. \* and \* \* may be caused by the impulsive perturb
