摘要
主要利用一元函数u(t)型积分平均辅助函数和广义Riccati变换技巧,建立带有强迫项的二阶拟线性微分方程α-1(p(t)|y′(t)y′(t))′+q(t)|y(t)|β-1|y(t)=e(t)的新的区间振动准则,去掉了某些已有结果中关于"φ′(t)≥0"的限制.
In this paper,by using integral averaging functions of the formu(t)and the generalized Riccati technique,new interval oscillation criteria areestablished for forced second-order quasi-linear differential equations of the form p(t)y′(t)α-1(y′(t))′+q(t)q(t)β-1 y(t)=e(t).We drop the restriction"φ′(t)≥0"in some existing results.
