1. Lyapunov inequalities and stability for discrete linear Hamiltonian systems.

Author

Zhang, Qi-ming and Tang, X. H.

Subjects
*LYAPUNOV stability, *MATHEMATICAL inequalities, *DISCRETE groups, *LINEAR algebraic groups, *HAMILTONIAN systems
Abstract

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. [ABSTRACT FROM PUBLISHER]

2. On Lyapunov-type inequalities for nonlinear dynamic systems on time scales

Author

Zhang, Qi-Ming, He, Xiaofei, and Jiang, Jianchu

Subjects
*LYAPUNOV functions, *MATHEMATICAL inequalities, *NONLINEAR systems, *NUMERICAL analysis, *DIFFERENTIAL equations, *SYSTEMS theory
Abstract

Abstract: In this paper, by using elementary analysis, we establish several new Lyapunov type inequalities for the following nonlinear dynamic system on an arbitrary time scale when the end-points are not necessarily usual zeros, but rather, generalized zeros, which generalize and improve all related existing ones including the continuous and discrete cases.
