Stability Analysis of a Multigroup Epidemic Model with General Exposed Distribution and Nonlinear Incidence Rates

open access: yesAbstract and Applied Analysis, 2013
We investigate a class of multigroup epidemic models with general exposed distribution and nonlinear incidence rates. For a simpler case that assumes an identical natural death rate for all groups, and with a gamma distribution for exposed distribution ...

A discrete logarithmic function and Lyapunov function

open access: yesJSIAM Letters, 2022
Summary: The Lyapunov function plays an important role in the stability theory of dynamical systems. Its counterpart for discrete dynamical systems is not studied so much, though importance of such systems is increasing. In this letter, an attempt is made to construct a discrete analog of the Lyapunov function for the competitive Lotka-Volterra ...

On Vector Lyapunov Functions [PDF]

open access: yesProceedings of the American Mathematical Society, 1971
It has been proved that the use of a vector Lyapunov function is more advantageous in certain situations rather than a scalar function. Moreover, each function needs to satisfy less rigid requirements. In this paper a new situation has been considered where vector Lyapunov functions play a further useful role. For this purpose, a new type of stability,

Some stability and boundedness criteria for a class of Volterra integro-differential systems

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2002
Using Lyapunov and Lyapunov-like functionals, we study the stability and boundedness of the solutions of a system of Volterra integrodifferential equations.

Learning lyapunov functions for hybrid systems [PDF]

open access: yesProceedings of the 24th International Conference on Hybrid Systems: Computation and Control, 2021
We propose a sampling-based approach to learn Lyapunov functions for a class of discrete-time autonomous hybrid systems that admit a mixed-integer representation. Such systems include autonomous piecewise affine systems, closed-loop dynamics of linear systems with model predictive controllers, piecewise affine/linear complementarity/mixed-logical ...

State Observation for Lipschitz Nonlinear Dynamical Systems Based on Lyapunov Functions and Functionals

open access: yesMathematics, 2020
State observers for systems having Lipschitz nonlinearities are considered for what concerns the stability of the estimation error by means of a decomposition of the dynamics of the error into the cascade of two systems. First, conditions are established

Asymptotic stabilization for nonlinear systems with time‐varying delays

open access: yesIET Control Theory & Applications, 2023
In this paper, asymptotic stabilization problem for a class of nonlinear systems with unknown time‐varying delays is addressed. With the introduced static gain functions and new Lyapunov–Krasovskii functionals, a novel output feedback control strategy is

Lyapunov functionals for the heat equation and sharp inequalities

open access: yesAtti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2013
The heat equation represents a powerful instrument to obtain a number of mathematical inequalities in sharp form. This may be not so well-known property goes back more or less to half a century ago, when independently from each others, researchers from ...

Stability bound analysis of singularly perturbed systems with time-delay [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2013
This paper considers the stability bound problem of singularly perturbed systems with time-delay. Some stability criteria are derived by constructing appropriate Lyapunov-Krasovskii functionals.
