✦ Synopsis

In this paper, two new oscillation criteria for forced second-order nonlinear differential equations of the form (~(,)~(~(~)) W(~)r -~ ~'(~))' + ~(~)i(~(,)) = e(~), ~ >_ ~o, are established. Our results are based on the information on a sequence of subintervals of [to, c~) 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].

By using the Riccati technique and the variational principle, new oscillation criteria are given for second-order quasi-linear differential equations with an oscillatory forcing term, which improve and generalize some new results from the literature. An (α + 1)-degree functional is involved in the o
