Abstract
We establish new Kamenev-type criteria for oscillation of the second-order linear differential equation, (p(t)xΔ(t))Δ + q(t)x(σ(t)) = 0, on a measure chain. Our results are extensions of those for differential equations and provide new oscillation criteria for difference equations. Several examples are given to show the significance of the results.
