Oscillation Criteria for Some Second-Order Superlinear Differential Equations

Resumo

We study a class of second-order superlinear equations. New oscillations criteria are established by using a general class of parameter functions in the averaging techniques. We extend and improve the oscillation criteria of several authors. One of our results is based on the information for the whole half line and the other is based on the information on a sequence subintervals of the whole half line.
