Existence Theorems of Periodic Solutions for Second-Order Nonlinear Difference Equations
The authors consider the second-order nonlinear difference equation of the type Δ(pn(Δxn−1)δ)+qnxnδ=f(n,xn),n∈ℤ, using critical point theory, and they obtain some new results on the existence of periodic solutions.
