Near-optimal control of a stochastic SICA model with imprecise parameters
Houssine Zine, Delfim F. M. Torres
An adequate near-optimal control problem for a stochastic SICA (Susceptible-Infected-Chronic-AIDS) compartmental epidemic model for HIV transmission with imprecise parameters is fo…
Weighted Generalized Fractional Integration by Parts and the Euler-Lagrange Equation
Houssine Zine, El Mehdi Lotfi, Delfim F. M. Torres +1
Integration by parts plays a crucial role in mathematical analysis, e.g., during the proof of necessary optimality conditions in the calculus of variations and optimal control. Mot…
Lyapunov Functions and Stability Analysis of Fractional-Order Systems
Adnane Boukhouima, Houssine Zine, El Mehdi Lotfi +3
This study presents new estimates for fractional derivatives without singular kernels defined by some specific functions. Based on obtained inequalities, we give a useful method to…
Stochastic SICA Epidemic Model with Jump Lévy Processes
Houssine Zine, Jaouad Danane, Delfim F. M. Torres
We propose and study a shifted SICA epidemic model, extending the one of Silva and Torres (2017) to the stochastic setting driven by both Brownian motion processes and jump Lévy no…
Modeling and Forecasting of COVID-19 Spreading by Delayed Stochastic Differential Equations
Marouane Mahrouf, Adnane Boukhouima, Houssine Zine +3
The novel coronavirus disease (COVID-19) pneumonia has posed a great threat to the world recent months by causing many deaths and enormous economic damage worldwide. The first case…
A stochastic time-delayed model for the effectiveness of Moroccan COVID-19 deconfinement strategy
Houssine Zine, Adnane Boukhouima, El Mehdi Lotfi +3
Coronavirus disease 2019 (COVID-19) poses a great threat to public health and the economy worldwide. Currently, COVID-19 evolves in many countries to a second stage, characterized…
