Oscillation criteria for a certain even order neutral difference equation with an oscillating coefficient
Concerning the difference equation \[ \Delta^n[y(k)+p(k)y(\tau(k))] +q(k)y (\sigma(k))=0 \] conditions are given such that every bounded solution is either oscillatory or tending to zero as \(k\to\infty\).
