Existence and Nonexistence of Periodic Solutions for a Class of Fourth-Order Partial Difference Equations
In this paper, we investigate multiplicity, existence, and nonexistence of periodic solutions to a fourth-order partial difference equation via linking theorem and saddle point theorem. Our obtained results significantly generalize and improve some existing ones. We also provide examples and numeric...
