Nontrivial Periodic Solutions to Some Semilinear Sixth-Order Difference Equations
We establish some new criteria to guarantee nonexistence, existence, and multiplicity of nontrivial periodic solutions of some semilinear sixth-order difference equations by using minmax method, Z2 index theory, and variational technique. Our results only make some assumptions on the period T, which...
