Dynamical Analysis of a Cocaine-Heroin Epidemiological Model with Spatial Distributions
Achraf Zinihi, Moulay Rchid Sidi Ammi, Matthias Ehrhardt +1
This article conducts an in-depth investigation of a new spatio-temporal model for the cocaine-heroin epidemiological model with vital dynamics, incorporating the Laplacian operato…
Global Existence of Solutions for a Fractional Caputo Nonlocal Thermistor Problem
Moulay Rchid Sidi Ammi, Ismail Jamiai, Delfim F. M. Torres
We begin by proving a local existence result for a fractional Caputo nonlocal thermistor problem. Then, additional existence and continuation theorems are obtained, ensuring global…
Diamond- Jensen's Inequality on Time Scales
Moulay Rchid Sidi Ammi, Rui A. C. Ferreira, Delfim F. M. Torres
The theory and applications of dynamic derivatives on time scales has recently received considerable attention. The primary purpose of this paper is to give basic properties of dia…
Necessary Optimality Conditions for a Dead Oil Isotherm Optimal Control Problem
Moulay Rchid Sidi Ammi, Delfim F. M. Torres
We study a system of nonlinear partial differential equations resulting from the traditional modelling of oil engineering within the framework of the mechanics of a continuous medi…
