On the oscillation of second-order nonlinear differential equations with damping
Süleyman Ögrekci; Adil Misir; Aydin Tiryaki;Abstract
In this paper, we are concerned with the oscillations in forced
second order nonlinear di¤erential equations with nonlinear damping terms.
By using clasical variational principle and averaging technique, new oscillation
criteria are established, which revise, improve and extend some recent results.
Furthermore our study answers the comment [13]. Examples are also given to
illustrate the results.
