Stochastic dynamics of an HIV/AIDS epidemic model with treatment

, 2019
We investigate a stochastic HIV/AIDS epidemic model with treatment. The model allows for two stages of infection namely the asymptomatic phase and the symptomatic phase. We prove existence of global positive solutions.

, 2008
We formulate a simple host-parasite type model to study the interaction of certain plant and herbivore. Our two dimensional discrete time model utilizes leaf and herbivore biomass as state variables. The parameter space consists of the growth rate of the

Discussion on the solutions to nonlinear singular systems with delay via LyapunovKrasovski approach

In this paper, some qualitative behaviors of nonlinear singular systems (NSSs) with time-varying delays are investigated. By means of the Lyapunov-Krasovski functional (LKF) approach, some solution estimates for the considered systems are generated.

Almost Sure Exponential Stability of Neutral Differential Difference Equations. . .

, 1996
: In this paper we shall discuss the almost sure exponential stability for a neutral differential difference equation with damped stochastic perturbations of the form d[x(t) \Gamma G(x(t \Gamma ø ))] = f(t; x(t); x(t \Gamma ø ))dt + oe(t)dw(t): Several ...

Stochastic Self-Stabilization

, 1996
: Given a nonlinear Ito equation dx(t)=f(x(t);t)dt+ug(x(t);t)dw(t), suppose that the equation is almost surely exponentially stable provided the noise intensity u is large enough.

Periodicity , positivity and stability of solutions for some delay dynamic equations using the fixed point technique

This thesis focuses on examining the periodicity, positivity, and stability of solutions for specific delay dynamic equations on time scales. To achieve this, we initially introduce fundamental concepts pertaining to functional analysis, fixed point ...
