Existence of uncountably many periodic solutions for second-order superlinear difference equations with continuous time

Due to the essential difficulty of establishing an appropriate variational framework on a suitable working space, how to apply the critical point theory for showing the existence and multiplicity of periodic solutions of continuous-time difference equations remains a completely open problem. New ide...
