Abstract:By using integral averaging techniques and generalized Riccati transformation, we obtain some new oscillation criteria for the second-order quasilinear differential equations r(t)|x'(t)|^α-1x'(t)]'+p(t)|x'(t)|α-1x'(t)+g(t)|x(t)|^β-1x(t)=0. The results improve and extend some known results of Kamenev ,Philos ,Wang and Xu.
Keywords:quasilinear differential equation  oscillation  integral averaging technique
