We obtain conditions for existence and (almost) non-oscillation of solutions of a second order linear homogeneous functional differential equations $u^{''} (x) + \sum_{i} p_{i} (x) u^{'} (h_{i} (x)) + \sum_{i} q_{i} (x) u (g_{i} (x)) = 0$ without the delay conditions $h_{i} (x), g_{i} (x) \leq x$ , $i = 1, 2, ...$ , and $u^{''} (x) + \int_{0}^{\infty} u^{'} (s) d_{s} r_{1} (x, s) + \int_{0}^{\infty} u (s) d_{s} r_{0} (x, s) = 0 .$

On oscillation and asymptotic property of a class of third order differential equations

N. Parhi, Seshadev Pardi (1999)

Czechoslovak Mathematical Journal

In this paper, oscillation and asymptotic behaviour of solutions of $y^{'''} + a (t) y^{''} + b (t) y^{'} + c (t) y = 0$ have been studied under suitable assumptions on the coefficient functions $a, b, c \in C ([σ, \infty), R)$ , $σ \in R$ , such that $a (t) \geq 0$ , $b (t) \leq 0$ and $c (t) < 0$ .

The paper deals with oscillation criteria of fourth order linear differential equations with quasi-derivatives.
