通过使用时标上的脉冲不等式和Riccati技巧,我们得到判断时标上带阻尼项的二阶脉冲动力方程解的振动性与渐近性的充分条件,推广并改进了已有文献中的相关结果.例子验证了我们的主要定理并表明了脉冲对方程振动性的影响.
By using an impulsive inequality and Riccati substitutions, we establish some new oscillation criteria for second-order nonlinear impulsive dynamic equations with damping on time scales. Some known results in the literatures are generalized and improved. Furthermore, an examples is given to illustrate our results.
