具连续偏差变元的二阶阻尼微分方程的振动性

摘要

获得一类具有连续偏差变元的非线性二阶阻尼泛函微分方程所有解振动的若干充分条件.所得结果包含和推广了已有文献中的相关结论,并给出2个应用实例.%We obtain sufficient conditions for the oscillation of all solutions of the nonlinear second-order damped functional differential equations with continuous deviating arguments. This work generalizes and improves some known results. The main results are illustrated by two examples.
