This paper is concerned with the oscillatory behavior of third order nonlinear neutral differential equations (r(t)((x(t)+p(t)x(τ(t)))"α)'+q(t)f(x(σ(t)))=0(E) where studied equation is in a noncanonical form, i.e., ∫_(t0)~∞ dt/r 1/α(t) < ∞. Some new oscillation criteria for Equation (E) are established. Examples illust...
