Most Probable Dynamics of the Single-Species with Allee Effect under Jump-diffusion Noise
Almaz Tesfay, Shenglan Yuan, Daniel Tesfay +1
We investigate the most probable phase portrait (MPPP) of a stochastic single-species model with the Allee effect using the non-local Fokker-Planck equation. This stochastic model…
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…
Escape Probability and Mean Residence Time in Random Flows with Unsteady Drift
Jinqiao Duan, James Brannan, Vincent Ervin
We investigate fluid transport in random velocity fields with unsteady drift. First, we propose to quantify fluid transport between flow regimes of different characteristic motion,…
