Lyapunov inequalities and stability for discrete linear Hamiltonian systems
Qiming Zhang, Xianhua Tang · The Journal of Difference Equations and Applications · 2011
In this paper, we establish several new Lyapunov-type inequalities for discrete linear Hamiltonian systems when the end-points are not necessarily usual zeros, but rather, generalized zeros, which generalize and improve almost all related existing ones. Applying these inequalities, an optimal stability criterion is obtained.
