By using the critical point method, some new criteria are obtained for
the existence and multiplicity of periodic and subharmonic solutions
to a 2nth-order nonlinear difference equation. The proof is based on
the Linking Theorem in combination with variational technique. Our
results generalize and improve some known ones.
