The unit bundle of a real hyperbolic space
Alfred Touré, Daniel Koama, Mikaïlou Compaoré, Marie Françoise Ouedraogo
The purpose of this article is to study the two homogeneous structures of the unit bundle UH^n of a real hyperbolic space. In both the cases, we determine the -invariant Riemannian metrics. In passing, we examine whether the geodesic flow is an isometry of UH^n when equipped with its Levi-Civita metric. Finally, we study the manifold of geodes(...)

Global existence of a weak solution for a reaction–diffusion system in a porous medium with membrane conditions and mass control
Safimba Soma , Siaka Kambele and Aboudramane Guiro
In this paper, we prove the global exstence of weak solutions for a porous medium
dynamics of m species moving between two domains separated by a zero-thickness membrane.
On this membrane, Kedem–Katchalsky conditions are considered, and the study is characterized
by natural structural conditions applied to the nonlinear reactive terms. The(...)

REMOVABLE SETS FOR THE WAVE EQUATIONS IN TERMS OF HAUSDORFF MEASURE
I.LY, M. OUEDRAOGO, B. BELLA and T.OUEDRAOGO
We prove a Radó theorem for the wave equations. Namely, we
consider u to be a locally Lipschitz continuous function on an
open set X of R^{n+1} and weakly solution to the wave equations ∂ttu -div(∇u)=0
away from the zero set away from the zero set u^{-1}(0) in X. We prove
that u is a weak solution to these wave equations in(...)

Hadarou YIOGO, Zoïnabo SAVADOGO
La situation sécuritaire au Burkina Faso s’est dégradée ces dernières
années. Cela a eu un impact négatif sur le système éducatif du pays à
travers la fermeture de plusieurs écoles. Compte tenu de
l’importance accordée à l’éducation, il est nécessaire de mettre en

EXTENSION OF THE SIMPLE MULTI-ATTRIBUTE RATING TECHNIQUE (SMART) TO GROUP DECISION PROBLEM SOLVING)
Hamado BAMOGO, Zoïnabo SAVADOGO
This study proposes an extension of the SMART (Simple MultiAttribute Rating Technique) method to adapt it to group decisions, a
context where classical methods often show their limits. To better
manage the diversity of preferences and complex interactions

NONREGULAR BOUNDARY VALUE PROBLEMS WITH A PARAMETER
I. Ly, T. Dabre and B. Bella
In this paper, we discuss boundary value problems for a class of
nonlinear elliptic equations with data on a boundary surface. We
denote by y the unknown function which is supposed to take its values
in R^k. We assume that only some components of y are given on
the whole boundary surface implying the designation of nonreg(...)

Mathematical Modeling and Optimal Control of an HIV/AIDS Transmission Model.
Ouedraogo Boukary, Zorom Malicki, Gouba Elisée
In this article, we present a mathematical model for the transmission of HIV with the compartment of
individuals in remission and vertical transmission describing the dynamics of the spread of the HIV/AIDS epidemic in
a community. In the mathematical analysis of the model, we compute the basic reproduction number R0 and study the
existen(...)

Analysis of the Well-posedness of a SEIRDS Dynamic Model for the Spread of Infectious Diseases
Siaka KAMBELE ; Safimba SOMA and Aboudramane GUIRO
The goal of this paper is to demonstrate the well-posedness of a nonlinear parabolic reaction-diffusion system modeling the
spread of infectious diseases. The considered mathematical model is of the SEIRDS type. We prove the global existence
of a weak solution by using an approximation system with a delay operator λτ (which we define in the s(...)

Détermination d'une meilleure variété de niébé pour promouvoir sa production à l'aide de la méthode EVAMIX et VMAVA+ au Burkina Faso
Hadarou YIOGO, Zoïnabo SAVADOGO
Au Burkina Faso, le niébé constitue une importante denrée alimentaire de base dans les ménages. Il
contribue fortement dans la nutrition des personnes, la sécurité alimentaire et la génération des ressources.
Ce qui rend sa culture incontournable. Malgré l'engouement des agriculteurs dans la culture du niébé, la

Résolution d’équations aux dérivées partielles d’ordre fractionnaire issus des ondes par la méthode SBA.
NEBIE Abdoul Wassiha
Les ondes constituent des perturbations se déplaçant dans un milieu, transportant de l'énergie sans transporter de matière. Elles sont classées en deux grandes catégories : les ondes mécaniques (comme les ondes sonores) dont la propagation nécessite un milieu matériel (solidegaz liquide) et les ondes électromagnétiques (comme la lumière et les(...)

Mathematical analysis of the effects of precarious health system on COVID-19 transmission dynamics: case of Burkina Faso
Ousmane Koutou, Komi Afassinou, Adama Ouedraogo, Abou Bakari Diabate
In the early moments of the pandemic of coronavirus disease 2019 (COVID-19), the level of e ectiveness in treatment and management of patients was limited due to the lack of e ective medications and adapted infrastructures in several countries especially in most developing countries. In this study, we propose an SIR-pattern model to investigat(...)
