Oscillation Criteria for Second Order Nonlinear Functional Different Equations

利用振动性理论研究了一类二阶非线性泛函微分方程解的振动性,获得这一类方程新的振动准则.这些准则改进和推广了现有结果.

Using the linear functional dif teria have extended theory of oscillation, the authors studied the oscillation criteria for second order non ferent equations. Some new oscillation criteria for equations were obtained. These cri and improved a number of the existing results.
