Abstract: This paper investigates the oscillation of third-order half linear neutral functional differential equations with damping. By introducing parameter function and the generalized Riccati transformation and using integral averaging technique and some necessary technique, some new sufficient conditions which ensure that any solution of such equation oscillates or converges to zero were proposed. The corresponding results in literature are extended and improved.

Key words: third-order neutral equations, half linear, damping terms, oscillation
