二阶非线性脉冲时滞微分方程的振动性

Oscillation of Second order Nonlinear Impulsive Delay Differential Equations

利用广义黎卡提变换得到了一类二阶非线性脉冲时滞微分方程所有解振动的充分条件,推广了Dz∨urina和Stavroulakis中关于非脉冲方程的相关结果.

Sufficient condtion for oscillation of all solutions of a class of second order nonlinear impulsive delay differential equation is obtained by using generalized Ricatti transform, which extend the corresponding results of Dzurina and Stavroulakis [Appl Math Comput, 2003,140, 445--453] for equations without impulsive effects.
