摘要: A new criterion is established for the oscillation of second order superlinear ordinary differential equations of the formx″(t)+ p(t)x′(t) + q(t)|x(t)|αsgnx(t) = 0, t ≥ t0,where α>1,p and q are continuous functions on [t0,∞). This criterion extends and unifies some of the results obtained in [1]- [5].
