Some oscillation criteria are established by Raccati transformation techniques
for the following second-order nonlinear neutral difference equation
△ (pn (△ (xn + cn xn - τ) )γ ) + qnxn - σβ = 0,n = 0, 1, 2,…
which extend and include several oscillation criteria in [11], and also correct a theorem and its proof in [10].
Key words： Oscillation; superlinear; sublinear; difference equations
