Graph Theoretic Technique to the Global Stability Analysis of the Discrete Age Structured SVEIR Model with Application to Ebola Virus Disease

Brenda Onyango, George O. Lawi & Frankline Tireito · Asian Research Journal of Mathematics · 2022

Discrete age structured models provide a better approach of discussing the spread of infectious diseases with infectivity, mortality and recovery being age dependent. Measures such as vaccination are carried out in discrete time or applied to individuals in certain age-groups. In...

Analysis of a Multiscale Model of Ebola Virus Disease

Duncan O. Oganga, George O. Lawi & Colleta A. Okaka · Asian Research Journal of Mathematics · 2020

Multiscale models are ones that link the epidemiological processes dealing with the transmission between hosts and the immunological processes dealing with the dynamics within one host. In this study, a multiscale model of Ebola Virus Disease linking epidemiological and immunolog...

Density Dependent Delayed Migration for Rosenzweig-Macaurther Model with Holling Type II Predator Functional Response

Samuel B. Apima, George O. Lawi & Nthiiri J. Kagendo · Asian Research Journal of Mathematics · 2019

The model describing the interaction between the predator and prey species is referred to as a predator-prey model. The migration of these species from one patch to another may not be instantaneous. This may be due to barriers such as a swollen river or a busy infrastructure thro...
