Abstract

In this paper, oscillation criteria are obtained for higher-order half-linear delay difference equations involving generalized difference operator of the form

Δb(pn(Δbm1xn)α)+qnxnσβ=0,  nn0,

where ∆b is defined by ∆byn = yn+1 - byn, b ∈ ℝ - {0}, p: ℕ → ℝ+, α, β are the ratio of odd positive integers with βα; m, n, n0, σ are non-negative integers, q: ℕ → ℝ. The cases of b negative and positive and qn ≥ 0, which has important role for oscillation of this equation, are considered. Also we provide some examples to illustrate our main results.
