Advances in difference equations IIAsymptotic and oscillatory behavior of solutions of general nonlinear difference equations of second order
Review articleOpen access

AbstractThe asymptotic and oscillatory behavior of solutions of some general second-order nonlinear difference equations of the form Δ(anh(yn+1)Δyn)+pnΔyn+qn+1f(yσ(n+1))=0,n∈Z is studied. Oscillation criteria for their solutions, when “pn” is of constant sign, are established. Results are also presented for the damped-forced equation Δ(anh(yn+1)Δyn)+pnΔyn+qn+1f(yσ(n+1))=en,n∈ZExamples are inserted in the text for illustrative purposes.
