A Lyapunov function and global properties for SIR and SEIR epidemiological models with nonlinear incidence

Mathematical Biosciences and Engineering, 2004
Explicit Lyapunov functions for SIR and SEIR compartmentalepidemic models with nonlinear incidence of the form $\beta I^p S^q$for the case $p \leq 1$are constructed. Global stability of the models is thereby established.

Global Exponential Attitude Tracking Controls on SO(3) [PDF]

, 2014
This paper presents four types of tracking control systems for the attitude dynamics of a rigid body. First, a smooth control system is constructed to track a given desired attitude trajectory, while guaranteeing almost semi-global exponential stability.

On the General Ericksen-Leslie System: Parodi's Relation, Well-posedness and Stability

, 2012
In this paper we investigate the role of Parodi's relation in the well-posedness and stability of the general Ericksen-Leslie system modeling nematic liquid crystal flows.

Global properties of delayed models for SARS-CoV-2 infection mediated by ACE2 receptor with humoral immunity

AIMS Mathematics
The coronavirus disease 2019 (COVID-19) is caused by a new coronavirus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). SARS-CoV-2 infects the epithelial (target) cells by binding its spike protein, S, to the angiotensin-converting ...

Model for hepatitis C virus transmissions

Mathematical Biosciences and Engineering, 2013
Hepatitis C virus (HCV) is a leading cause of chronic liver disease. Thispaper presents a deterministic model for HCV infection transmission and usesthe model to assess the potential impact of antiviral therapy.

Symplectic Approach to Global Stability

We present a new approach to the problem of proving global stability, based on symplectic geometry and with a focus on systems with several conserved quantities. We also provide a proof of instability for integrable systems whose momentum map is everywhere regular.

Delayed population models with Allee effects and exploitation

Mathematical Biosciences and Engineering, 2014
Allee effects make populations more vulnerable to extinction, especially under severe harvesting or predation. Using a delay-differential equation modeling the evolution of a single-species population subject to constant effort harvesting, we show that

Stability of the global attractor under Markov-Wasserstein noise [PDF]

, 2011
We develop a "weak Wa\.zewski principle" for discrete and continuous time dynamical systems on metric spaces having a weaker topology to show that attractors can be continued in a weak sense.
