## Abstract Oscillation criteria for selfβadjoint fourthβorder differential equations were established for various conditions on the coefficients __r__(__x__) > 0, __q__(__x__) and __p__(__x__). However, most of these results deal with the case when lim~__x__ β β~β«^__x__^~1~__q__(__s__)β__ds__ < +
## Abstract We give constructive proof of the existence of vanishing at infinity oscillatory solutions for a secondβorder perturbed nonlinear differential equation. In contrast to most results reported in the literature, we do not require oscillatory character of the associated unperturbed equation
