Özet

We present new oscillation criteria for the second-order nonlinear differential equations. These criteria involve the use of averaging functions. Our theorems are stated in general form; they complement and extend related results known in the literature. Also, the relevance of our results is to show that some of Manojlovic's results contain the superfluous condition. (C) 2004 Elsevier Ltd. All rights reserved.
