摘要
利用函数类、算子方法和广义Riccati变换研究了二阶非线性微分方程(r(t)y'(t))'+Q(t,y(t),y'(t))=0,t≥t0的振动性,给出了Kamenev型振动准则,改进和推广了现有的若干结论.
This paper mainly studies the oscillation of second order nonlinear differential equation 0(r(t)y′(t))′+Q(t,y(t),y′(t))=0,t≥tby applying the function class, operator method and generalized Riccati transformation, we gives Kamenev-type oscillation criteria. The obtained results extend and improve the existing results.
