We study the half-linear neutral differential equation where Φ(t) = |t| p−2 t. We present new oscillation criteria for this equation in case when σ(τ(t)) = τ(σ(t)) and ∞ r 1−q (t)dt < ∞, q = p/(p − 1), p ≥ 2 is a real number. The results of this paper complement our previous results in case when the above integral is divergent and/or the deviations τ, σ commute with respect to their composition.
