一类二阶混合非线性微分方程的振动准则

Oscillation Criteria for a Class of Se-cond-Order Mixed Nonlinear Differential Equations

运用积分平均技巧和新型的核函数,结合Elure积分,得到一类二阶混合非线性阻尼方程的新振动准则。新的结果具有更高的一般性,并能得到解的零点分布信息。

New oscillation criteria for a class of second-order mixed nonlinear damping equations are obtained by means of the integral averaging technique and a new kernel function combined with the Elure integral.The new results have a higher generality than some of previous results.The zero distribution information of the solution is also obtained.
