Global Stability Analysis of HIV+ Model [PDF]

open access: yes13th International Conference on Theory and Application of Fuzzy Systems and Soft Computing — ICAFS-2018, 2018
We developed and studied a mathematical model of HIV+. Two equilibriums points were found, disease free and endemic equilibrium, and basic reproduction ratio [Formula: see text] was also calculated by the use of next generation matrix. Global stability analysis of the equilibria was carried out by the use of Lyapunov function, and it was shown that the

Dynamics of heterogeneous population due to spatially distributed parameters and an ideal free pair

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
Population movements are necessary to survive the individuals in many cases and depend on available resources, good habitat, global warming, climate change, supporting the environment, and many other issues.

Global Stability of a Humoral Immunity COVID-19 Model with Logistic Growth and Delays

open access: yesMathematics, 2022
The mathematical modeling and analysis of within-host or between-host coronavirus disease 2019 (COVID-19) dynamics are considered robust tools to support scientific research.

Stability of Global Monopoles Revisited [PDF]

open access: yesPhysical Review Letters, 2000
We analyze the stability of global O(3) monopoles in the infinite cutoff (or scalar mass) limit. We obtain the perturbation equations and prove that the spherically symmetric solution is classically stable (or neutrally stable) to axially symmetric, square integrable, or power-law decay perturbations.

Global Stability of Delayed SARS-CoV-2 and HTLV-I Coinfection Models within a Host

open access: yesMathematics, 2022
The aim of the present paper is to formulate two new mathematical models to describe the co-dynamics of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and human T-cell lymphotropic virus type-I (HTLV-I) in a host.

Dynamical Behavior of a Fractional Order Model for Within-Host SARS-CoV-2

open access: yesMathematics, 2022
The prime objective of the current study is to propose a novel mathematical framework under the fractional-order derivative, which describes the complex within-host behavior of SARS-CoV-2 by taking into account the effects of memory and carrier.

Global Properties of Cytokine-Enhanced HIV-1 Dynamics Model with Adaptive Immunity and Distributed Delays

open access: yesComputation, 2023
In this paper, we study a model that enhances our understanding of cytokine-influenced HIV-1 infection. The impact of adaptive immune response (cytotoxic T lymphocytes (CTLs) and antibodies) and time delay on HIV-1 infection is included.

Global Stability in Large Economies

open access: yesEconomic Theory Bulletin, 2023
Abstract A result is obtained showing how global stability of equilibrium, under the standard tâtonnement dynamic, arises in large economies having a continuous, diffuse distribution of consumers, as well as many goods.
