On oscillatory fourth order nonlinear neutral differential equations II

Rok, strany: 2005, 183 - 202

Oscillatory and asymptotic behaviour of solutions of a class of nonlinear fourth order neutral differential equations of the form

$$ (r(t)(y(t)+p(t)y(t-τ))'' )'' +q(t)G (y(t - σ)) = 0 $$

and

$$   (r(t)(y(t)+p(t)y(t-τ))'' )'' +q(t)G (y(t - σ )) = f(t) \tag"$(*)$" $$

are studied under the assumption $\int₀^∞ t/r(t) d t = ∞ $ for various ranges of $p(t)$. Sufficient conditions are obtained for the existence of bounded positive solutions of $(*)$.
