On oscillatory fourth order nonlinear neutral differential equations I

2004
Summary: Here, oscillatory and asymptotic properties of solutions of the classes of fourth order neutral differential equations \[ \bigl (r(t)\bigl (y(t)+p(t) y(t-\tau)\bigr)''\bigr)'' + q(t) G \bigl (y(t - \sigma)\bigr) = f(t) \tag{*} \] and \[ \bigl (r(t)\bigl (y(t)+p(t)y(t-\tau)\bigr)''\bigr)'' + q(t) G \bigl (y(t - \sigma)\bigr) = 0 \] are studied ...
