Multiple Periodic Solutions for Difference Equations with Double Resonance at Infinity

<p/> <p>By using variational methods and Morse theory, we study the multiplicity of the periodic solutions for a class of difference equations with double resonance at infinity. To the best of our knowledge, investigations on double-resonant difference systems have not been seen in the l...
