| Abstract | In this article, we study delay differential equations having forms
$x'(t) + P(t)x(t-\tau) - Q(t)x(t-\tau) = 0$ $[x(t) - R(t)x(t-\rho)]' + P(t)x(t-\tau) = 0$ and $[x(t)-R(t)x(t-\rho)]' + P(t)x(t-\tau) - Q(t)x(t-\sigma) = 0,$ where $P,Q,R \in C([t_0, \infty), \mathbb{R}^+)$ and $\tau, \sigma, \rho \ge 0$. We use recursive methods to obtain new oscillation criterions. |
