Studies On Oscillation For Second-order Nonlinear Differential Equations

The oscillation of ordinary differential equation is one of important branche of Differential equations. With the increasing development of science and technology, There are many problems relating to differential equation derived form lots of practi- cal applications, such as whether differential equation has a oscillating solution or not, and whether all of its solutions are oscillatory or not. In very resent years ,great chan- ges of this field have taken place. Especially, the second order differential equation has been paid more attentions and investigated in various classes by using different methods. The present paper investigate the oscillation criteria for some class of nonlinear differential equations...
