摘要
研究了具非线性中立项的一类二阶广义Emden-Fowler型泛函微分方程的振动性,考虑方程是非正则的情形(即∫t0^+∞a^-1/β(t)dt<+∞的情形),利用广义黎卡提变换技术及不等式技巧,获得了方程振动的几个新型的判别准则.
We analyze the oscillatory behavior of certain second-order generalized EmdenFowler-type differential equations with a quasilinear neutral term in this article,where investigated equation is in a noncanonical form,i.e.,∫t0^+∞ a^-1/β(t)dt<+∞.By using the generalized Riccati transformation and inequality technique,we establish some new oscillation criterions for the equations.
