We present new oscillation criteria for certain classes of second-order nonlinear differential equations and delay differential equations obtained by using an integral averaging technique. Our theorems complement a number of existing results and handle the cases which are not covered by known criter

In this paper, we discuss the oscillatory behavior of a certain nonlinear perturbed dynamic equation on time scales. We establish some new oscillation criteria for such dynamic equations and supply examples. (~) 2004 Elsevier Ltd. All rights reserved.
We present new oscillation criteria for the second order nonlinear perturbed differential equations. These criteria are of a high degree of generality and they extend and unify a number of existing results.
## Abstract In this paper, we consider the oscillation of the nonlinear differential equation We obtain a new sufficient condition for any nonoscillatory solution __y__(__t__) of the above equation satisfying lim inf~__t__ββ~ |__y__(__t__)| = 0. (Β© 2005 WILEYβVCH Verlag GmbH & Co. KGaA, Weinheim)
