Abstract: By employing a generalized Riccati technique and an integral averaging technique, new interval oscillation criteria are established for the forced second-order half-linear differential equation [r(t)|x’(t)|^α-1x’(t)]’+q(t)|x(t)|^α-1x(t)=e(t).

Key words: Half-linear differential equations, oscillation, interval criteria, generalized Ric- cati technique
