Summary
This paper deals with the oscillation and the asymptotic behavior of the solutions of superlinear differential equations with general (retarded, advanced or mixced type) deviating arguments. The equations considered involve a damping term. The results obtained extend known fundamental oscillation criteria for superlinear differential equations without damping terms and especially the recent basic reults of Kitamura and Kusano [5], and Staikos [19, 20].
