某类二阶非线性时滞微分方程的振动性
Oscillation of Second Order Nonlinear Delay Differential Equation
【摘要】 讨论了一类非线性项具时滞的二阶中立型微分方程的振动性,得到了所研究方程振动的三个充分条件.所得结论推广了已有的相应结论.
【Abstract】 This paper dicusses the oscillation of one kind of second-order nonlinear neutral delay differential equation.Three sufficient conditions in all solutions of the equation oscillate is obtained.The conclusions which we draw generalize the former conclusions.
