Using trigonometrical series theory and contraction mapping principle, This paper study two Discrete difference systems, sufficient and necessary conditions on the existence of periodic solutions for ...
Limit-circle invariance of non-symmetric discrete Hamiltonian systems
difference operator deficiency index non-symmetric
2011/10/12
In this paper, we first give the related important Lemmas, and after discusses the non-symmetric discrete Hamiltonian system, and obtain the limit-circle invariance theorem. The main results contain c...
