Abstract:Using the integral average method, we establish some oscillation criteria of Kamenev type and Yan type for the nonlinear system of differential equation
where the functions bi(t) (i = 1, 2) are nonnegative and summable on each finite segment of the interval Z0, ∞), λi > 0 (i = 1,2) with λ1 λ2 = 1.
Keywords:oscillation   Kamenev type   Yan type   Nonlinear system
