摘要
研究了一类二阶非线性阻尼微分方程解的振动性,建立了三个新的振动性定理,推广了Cecchi M和Marini M(Rocky Mount J Math,1992,22:1259-1276)的结果.
In this paper, we present some criteria for the oscillation of a class of the second order nonlinear differential equations with damping. The results generalize the known results of Cecchi M and Marini M (Rocky Mount J Math 22 (1992), 1259-1276).
