Global Stabilization of Triangulated Formations [PDF]
SIAM Journal on Control and Optimization, 2017 Formation control deals with the design of decentralized control laws that stabilize mobile, autonomous agents at prescribed distances from each other. We call any configuration of the agents a target configuration if it satisfies the inter-agent distance conditions. It is well known that when the distance conditions are defined by a rigid graph, there

The global stability of M33: still a puzzle [PDF]
, 2019 The inner disc of the local group galaxy M33 appears to be in settled rotational balance, and near IR images reveal a mild, large-scale, two-arm spiral pattern with no strong bar.

Almost Global Stability of Nonlinear Switched Systems With Time-Dependent Switching
IEEE Transactions on Automatic Control, 2018 For a dynamical system, it is known that the existence of a Lyapunov density implies almost global stability of an equilibrium. It is then natural to ask whether the existence of multiple Lyapunov densities for a nonlinear switched system implies almost ...

A General Multipatch Model of Ebola Dynamics
Nonautonomous Dynamical Systems, 2021 A model for the transmission dynamics of Ebola virus in a multipatch network setting is studied. The model considers the contribution to the dynamics by people who are susceptible, infectious, isolated, deceased but still infectious and not yet buried ...

On the practical global uniform asymptotic stability of stochastic differential equations [PDF]
, 2015 The method of Lyapunov functions is one of the most effective ones for the investigation of stability of dynamical systems, in particular, of stochastic differential systems.

Global stability of a delayed and diffusive virus model with nonlinear infection function
Journal of Biological Dynamics, 2021 This paper studies a delayed viral infection model with diffusion and a general incidence rate. A discrete-time model was derived by applying nonstandard finite difference scheme. The positivity and boundedness of solutions are presented.

An SEIR model with infectious latent and a periodic vaccination strategy
Mathematical Modelling and Analysis, 2021 An SEIR epidemic model with a nonconstant vaccination strategy is studied. This SEIR model has two disease transmission rates β1 and β2 which imitate the fact that, for some infectious diseases, a latent person can pass the disease into a susceptible one.

Stability as a natural selection mechanism on interacting networks [PDF]
, 2010 Biological networks of interacting agents exhibit similar topological properties for a wide range of scales, from cellular to ecological levels, suggesting the existence of a common evolutionary origin.

Global stability of the positive equilibrium for a non-cooperative model of nuclear reactors
Electronic Journal of Qualitative Theory of Differential Equations, 2012 In this paper, we investigate the non-cooperative reaction-diffusion model of nuclear reactors subject to the homogeneous Neumann boundary condition. By establishing appropriate Lyapunov functions, we prove the global stability of the unique positive ...
