Sentence examples for existing oscillation from inspiring English sources

Our main goal is to state a new oscillation theorem for Equation (1) in the sublinear case λ < α β γ and to extend the existing oscillation results in the literature in case where the difference operator in (1) is in the canonical form, i.e., when ∑ n = n 0 ∞ a n − 1 / α = ∑ n = n 0 ∞ b n − 1 / β = ∑ n = n 0 ∞ c n − 1 / γ = ∞.
