Weak solutions for coupled reaction-diffusion systems with pattern formation by a stochastic fixed point theorem
Erika Hausenblas, Michael A. Högele, Tesfalem A. Tegegn
Chemical and biochemical reactions can exhibit surprisingly different behaviours, ranging from multiple steady-state solutions to oscillatory solutions and chaotic behaviours. Thes…
Contribution of the 2021 COVID-19 Vaccination Regime to COVID-19 Transmission and Control in South Africa: A Mathematical Modeling Perspective
Tesfalem Abate Tegegn, Yibeltal Adane Terefe
This study assesses the impact of COVID-19 vaccines through an epidemiological model that quantifies their role in pandemic control. We analyze an SIR-based model incorporating vac…
On the inertial range bounds of K-41 like Magnetohydrodynamics turbulence
Tesfalem Abate Tegegn
The spectral slope of Magnetohydrodynamic (MHD) turbulence varies depending on the spectral theory considered; is the spectral slope in Kraichnan-Iroshnikov-Dobrowolny (KI…
Large, moderate deviations principle and -limit for the 2D Stochastic LANS-
Z. I. Ali, P. A. Razafimandimby, T. A. Tegegn
In this paper we consider the Lagrangian Averaged Navier-Stokes Equations, also known as, LANS- Navier-Stokes model on the two dimensional torus. We assume that the noise is a c…
