Oscillations of certain functional differential equations

Said R. Grace (1999)

Czechoslovak Mathematical Journal

Sufficient conditions are presented for all bounded solutions of the linear system of delay differential equations ${(- 1)}^{m + 1} \frac{d^{m} y_{i} (t)}{d t^{m}} + \sum_{j = 1}^{n} q_{i j} y_{j} (t - h_{j j}) = 0, m \geq 1, i = 1, 2, ..., n,$ to be oscillatory, where $q_{i j} ε (- \infty, \infty)$ , $h_{j j} \in (0, \infty)$ , $i, j = 1, 2, ..., n$ . Also, we study the oscillatory behavior of all bounded solutions of the linear system of neutral differential equations ${(- 1)}^{m + 1} \frac{d^{m}}{d t^{m}} (y_{i} (t) + c y_{i} (t - g)) + \sum_{j = 1}^{n} q_{i j} y_{j} (t - h) = 0,$ where $c$ , $g$ and $h$ are real constants and $i = 1, 2, ..., n$ .

Oscillations of higher order differential equations of neutral type

N. Parhi (2000)

Czechoslovak Mathematical Journal

In this paper, sufficient conditions have been obtained for oscillation of solutions of a class of $n$ th order linear neutral delay-differential equations. Some of these results have been used to study oscillatory behaviour of solutions of a class of boundary value problems for neutral hyperbolic partial differential equations.
