Dynamics of a Stochastic COVID-19 Epidemic Model with Jump-Diffusion
Almaz Tesfay, Tareq Saeed, Anwar Zeb +3
For a stochastic COVID-19 model with jump-diffusion, we prove the existence and uniqueness of the global positive solution. We also investigate some conditions for the extinction a…
Stochastic Bifurcation in Single-Species Model Induced by α-Stable Levy Noise
Almaz Tesfay, Daniel Tesfay, Shenglan Yuan +2
Bifurcation analysis has many applications in different scientific fields, such as electronics, biology, ecology, and economics. In population biology, deterministic methods of bif…
A Logistic-Harvest Model with Allee Effect under Multiplicative Noise
Almaz Tesfay, Daniel Tesfay, James Brannan +1
This work is devoted to the study of a stochastic logistic growth model with and without the Allee effect. Such a model describes the evolution of a population under environmental…
Mean Exit Time and Escape Probability for the Stochastic Logistic Growth Model with Multiplicative α-Stable Lévy Noise
A. Tesfay, D. Tesfay, A. Khalaf +1
In this paper, we formulate a stochastic logistic fish growth model driven by both white noise and non-Gaussian noise. We focus our study on the mean time to extinction, escape pro…
