Time-oscillating Lyapunov modes and auto-correlation functions for quasi-one-dimensional systems
The time-dependent structure of the Lyapunov vectors corresponding to the steps of Lyapunov spectra and their basis set representation are discussed for a quasi-one-dimensional many-hard-disk systems. Time-oscillating behavior is observed in two types of

Economic MPC of Nonlinear Systems with Non-Monotonic Lyapunov Functions and Its Application to HVAC Control [PDF]
This paper proposes a Lyapunov-based economic MPC scheme for nonlinear sytems with non-monotonic Lyapunov functions. Relaxed Lyapunov-based constraints are used in the MPC formulation to improve the economic performance. These constraints will enforce a Lyapunov decrease after every few steps.

Lyapunov functions and isolating blocks
Let M denote a smooth (Cm) n-dimensional manifold and let $: M x R -+ M denote a Cr flow (or dynamical system) which is generated by a CT vector field 4 (= (d/dt) +(t, x) j t = 0) on M (0 max(1, r}. In this case, we can only obtain Ck smoothness for functions on M. Let K denote a compact invariant set for ‘p, i.e., K is a compact subset of M and if x

Global finite-time stability of differential equation with discontinuous right-hand side
In the paper new sufficient conditions for global finite-time stability of a stationary solution to differential equation with discontinuous right-hand side are given. Time-dependent Lyapunov function which is only continuous is used.

Asymptotic behavior of a stochastic delayed avian influenza model with saturated incidence rate
In this paper, we establish a stochastic delayed avian influenza model with saturated incidence rate. Firstly, we prove the existence and uniqueness of the global positive solution with any positive initial value.

Path-Complete Graphs and Common Lyapunov Functions [PDF]
A Path-Complete Lyapunov Function is an algebraic criterion composed of a finite number of functions, called its pieces, and a directed, labeled graph defining Lyapunov inequalities between these pieces. It provides a stability certificate for discrete-time switching systems under arbitrary switching.

SOS-Convex Lyapunov Functions and Stability of Difference Inclusions [PDF]
We introduce the concept of sos-convex Lyapunov functions for stability analysis of both linear and nonlinear difference inclusions (also known as discrete-time switched systems). These are polynomial Lyapunov functions that have an algebraic certificate of convexity and that can be efficiently found via semidefinite programming.

Lyapunov-like functions involving Lie brackets [PDF]
For a given closed target we embed the dissipative relation that defines a control Lyapunov function in a more general differential inequality involving Hamiltonians built from iterated Lie brackets. The solutions of the resulting extended relation, here called degree-k control Lyapunov functions (k>=1), turn out to be still sufficient for the system ...

A graph-theoretic approach to global input-to-state stability for coupled control systems
In this paper, the input-to-state stability for coupled control systems is investigated. A systematic method of constructing a global Lyapunov function for the coupled control systems is provided by combining graph theory and the Lyapunov method ...
