## Abstract In this paper, we establish some new criteria for the oscillation of second order forced nonlinear differential equations (__r__ (__t__ )__x__ β²(__t__ ))β² + __p__ (__t__ )__x__ β²(__t__ ) + __q__ (__t__ )__f__ (__x__ (__t__ )) = __e__ (__t__ ) in both cases when __q__ (__t__ ) < 0 and __

## Introdiiction In [l], D. C. ANGELOVA and D. D. BAINOV consider the problem of boundedness and asymptotic behavior of the oscillatory solutions of some forced functional differential equations of second order. Their general equation is stated below in Theorem 1, as equation (I). There is a wealt
nis odd and a s " 1, are established. Here, we require the function f to be locally of bounded variation.
## 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
