A sharp oscillation criterion for a difference equation with constant delay

Abstract It is known that all solutions of the difference equation Δ x ( n ) + p ( n ) x ( n − k ) = 0 , n ≥ 0 , $$\Delta x(n)+p(n)x(n-k)=0, \quad n\geq0, $$ where { p ( n ) } n = 0 ∞ $\{p(n)\}_{n=0}^{\infty}$ is a nonnegative sequence of reals and k is a natural number, oscillate if lim inf n → ∞ ∑...
