On the 2D Ericksen–Leslie equations with anisotropic energy and external forces
Autor: Gabriel Deugoue, Paul André Razafimandimby, Zdzisław Brzeźniak
Publikováno v: Journal of Evolution Equations. 21:3891-3961
In this paper we consider the 2D Ericksen–Leslie equations which describe the hydrodynamics of nematic liquid crystal with external body forces and anisotropic energy modeling the energy of applied external control such as magnetic or electric fiel

Large deviation for a 2D Allen–Cahn–Navier–Stokes model under random influences
Autor: T. Tachim Medjo, Gabriel Deugoue
Publikováno v: Asymptotic Analysis. 123:41-78
In this article, we derive a large deviation principle for a 2D Allen–Cahn–Navier–Stokes model under random influences. The model consists of the Navier–Stokes equations for the velocity, coupled with an Allen–Cahn equation for the order (p

Strong solutions for the stochastic Cahn-Hilliard-Navier-Stokes system
Autor: A. Ndongmo Ngana, Gabriel Deugoue, T. Tachim Medjo
Publikováno v: Journal of Differential Equations. 275:27-76
A well-known diffuse interface model consists of the Navier-Stokes equations for the average velocity, nonlinearly coupled with a convective Cahn-Hilliard type equation for the order (phase) parameter. This system describes the evolution of an incomp

On the convergence of solutions of globally modified magnetohydrodynamics equations with locally Lipschitz delays terms
Autor: Gabriel Deugoue, Jules Djoko Kamdem, A. C. Fouape
Publikováno v: Quaestiones Mathematicae; Vol. 45 No. 4 (2022); 627-653
Existence and uniqueness of strong solutions for the three dimensional system of globally modified magnetohydrodynamics equations with locally Lipschitz delays terms are established in this article. Galerkin's method and Aubin Lions compactness theor

GLOBALLY MODIFIED NAVIER-STOKES EQUATIONS COUPLED WITH THE HEAT EQUATION: EXISTENCE RESULT AND TIME DISCRETE APPROXIMATION
Autor: J.K. Djoko, Gabriel Deugoue, A. C. Fouape
Publikováno v: Journal of Applied Analysis & Computation. 11:2423-2458
We provide in this article an investigation of the globally modified Navier-Stokes problem coupled with the heat equation. After deriving the variational formulation of this problem, we prove the existence and the uniqueness of the solution using the

Fully discrete finite element approximation of the stochastic Cahn–Hilliard–Navier–Stokes system
Autor: T. Tachim Medjo, Gabriel Deugoue, B. Jidjou Moghomye
Publikováno v: IMA Journal of Numerical Analysis. 41:3046-3112
In this paper we study the numerical approximation of the stochastic Cahn–Hilliard–Navier–Stokes system on a bounded polygonal domain of $\mathbb{R}^{d}$, $d=2,3$. We propose and analyze an algorithm based on the finite element method and a sem
