Özet

Some new oscillation criteria are given for second order nonlinear differential equations with damping of the form (gamma (t) x')' + p (t) x' + q (t) f (x) = 0. Our results are to develop oscillation criteria without any restriction on the signs of p (t) and q (t). These results generalize and extend some earlier results of Abdullah [1] and Zheng and Liu [12].
