Abstract :
In this paper the oscillation criterion was investigated for all solutions of the third-order half linear neutral differential equations. Some necessary and sufficient conditions are established for every solution of (a(t)(x(t)+p(t)x(t))γ)+q(t)xγ(б(t))=0,t≥t0, to be oscillatory. Examples are given to illustrate our main results
