Oscillation criteria for certain forced second-order nonlinear differential equations Original Research Article

In this paper, two new oscillation criteria for forced second-order nonlinear differential equations of the form View the MathML source are established. Our results are based on the information on a sequence of subintervals of [t0, ∞) only, rather than on the whole half-line. Our methodology is somewhat different from that of previous authors. The results presented here are much more general than a recent result of Li and Cheng [1].
