【Abstract】 In this paper, oscillatory and asymptotic behavior of solutions of the second order nonlinear differential equation(a(t)(y’(t))σ)’ + q(t)f(y(t)) = 0, t ≥t0are considered, where σ is a positive quotient of even over odd integers. The results obtained are new and one of them revises wong’s result.更多还原
