Discrete Riccati and Comparison Approaches to Oscillation of Second-Order Advanced Difference Equations with Multiple Deviating Arguments

In this work, we develop, from first principles, a discrete oscillation theory for second-order nonlinear advanced difference equations with several deviating arguments, Δr(n)(Δy(n))α+∑i=1mqi(n)Fy(σi(n))=0,σi(n)≥n, studied under the canonical condition ∑s=n0∞r−1/α(s)=∞. This equa...
