Malaria remains a major public health challenge in Benin, particularly among children under
five years of age. Despite the wide deployment of vector control measures the disease burden
remains high. Based on modeling approach, this study evaluates the potential impact and
effectiveness of the introduction of the RTS, S/ASO1 malaria vaccine(...)

Modeling and Mathematical Analysis of the Interactions Between the Leafhopper Amrasca Biguttula and Cotton Using Caputo's Fractional Approach
Soumaye HARO, Elisée GOUBA, Boukary OUEDRAOGO
In this paper, we propose a fractional order mathematical model in the sense of Caputo for the transmission dynamics of cotton disease caused by the jassid Amrasca biguttula. In this model, which takes into account disease transmission through vegetative reproduction, the cotton population is divided into susceptible (S_c), latent (L_c), and i(...)

Low-Regret Control of a Nonlinear Hyperbolic Problem With Missing Data.
Biéliémi LAMIEN, Sadou TAO, Satafa SANOGO.
In this paper, we characterise the control of an ill-posed nonlinear evolution problem. More precisely, we study the
low-regret control of a system governed by a hyperbolic operator by using the regularisation approach, which makes
it possible to generate missing data. We obtain singular optimal systems characterising the low-regret control(...)

Isotropic problem with non homogeneous Dirichlet boundary condition and L1-data
Boureima SAWADOGO, Stanislas OUARO, Adama KABORE
The purpose of this paper is to study an isotropic problem with non homogeneous Dirichlet
boundary condition and L1-data in a variable-exponent Sobolev space. We start by showing
the existence and uniqueness of the weak solution when the source term is bounded. Finally,
we use a problem-based approach to prove the existence and uniqueness o(...)

Analysis of the HIV/AIDS transmission dynamics model using Caputo fractional-order derivative
Boukary Ouedraogo , Nour Eddine Alaa , Elisée Gouba , Soumaye HARO
Although national and international institutions, such as the World Health Organization (WHO) and UNAIDS, are making significant efforts to eradicate HIV by 2030, it remains a major threat to global public health. Despite its low prevalence, HIV continues to claim lives and remains a major public health issue, especially in developing countrie(...)

Nonlinear Elliptic Problem Involving Natural Growth Term, Measure Data, Variable Exponent and Neumann Boundary Conditions
Ibrahim KONATE, Stanislas OUARO
In this paper, we investigate the existence of solutions to an elliptic problem with natural growth term, diffuse measure data and Neumann boundary conditions. Using approxi- mation methods via Yosida regularization and truncation, along with maximal monotone operator methods in Banach spaces, we prove the existence of a renormalized solution.(...)

Diffusive convective elliptic problem in variable exponent space and measure data
Safimba Soma , Ibrahime Konaté and Adama Kaboré
In this article, we study a class of convective diffusive elliptic problem with Dirichlet
boundary condition and measure data in variable exponent spaces. We begin by introducing an
approximate problem via a truncation approach and Yosida’s regularization. Then, we apply the
technique of maximal monotone operators in Banach spaces to obtain(...)

Extension of the Risk Model From a Hawkes Variable Memory Process via the Spearman Copula
Souleymane Badini, Frédéric Béré, Delwendé Abdoul-Kabir Kafando, Abdoul Karim Drabo
The ultimate ruin probability of an insurance company throughout its operating life remains and continues to be a major and very complex concern for the latter. Although this probability of ruin can be modeled using stochastic processes, its determination remains particularly complex. This mathematical complexity represents a considerable obst(...)

Implementation of an Innovative Method in the Field Of Social Choice Theory Based on the Geometric Mean
Zoïnabo Savadogo, Younoussa Sare, Elisée Gouba
Social choice theory, also known as voting methods theory, studies the mechanisms for aggregating individual preferences within a group into a collective decision. Among classical approaches, approval voting stands out for its simplicity and interesting theoretical properties. With the aim of improvement, particularly in terms of consensus and(...)

ANALYTICAL APPROXIMATION OF THE TIME-FRACTIONAL BURGERS EQUATION USING THE LAPLACE-SBA METHOD
Bayalla Bazoboué Laurent* , Sawadogo Salomond, Bamogo Hamadou et Francis Bassono
This paper investigates the application of the Laplace-SBA method to a nonlinear Burgers-type equation with a fractional time derivative in the sense of Caputo. Such equations, which incorporate memory effects and nonlocal behavior, are increasingly used to model

Optimal control and global dynamics of a fractional-order model incorporating general incidence and vaccination coverage
Téwendé Emmanuel Nana, Boureima Sangaré & Abou Bakari Diabaté
This work presents a fractional-order mathematical model featuring a generalized incidence function, designed to encapsulate the inherent memory effects observed in biological systems. The model incorporates partial vaccination coverage and accounts for complex transmission pathways, thereby elucidating critical yet often neglected mechanisms(...)

Weak solutions of a discrete Robin problem involving the anisotropic $\vect{p}$-mean curvature operator
B. Moussa, I. Nyanquini, S. Ouaro
This work investigates the existence and uniqueness of a so- lution to a discrete Robin boundary value problem involving the anisotropic p⃗-mean curvature operator. The existence re- sult is established through variational methods, specifically by applying the Mountain Pass Theorem of Ambrosetti and Rabinowitz in combination with Ekeland’s Var(...)

On Skew Cyclic Reversible DNA Codes Over F4[v]/⟨v4 − v⟩
Joel KABORE, Mohammed Elhassani Charkani
In this paper, we study a specific class of skew cyclic codes over the ring F_4[v]/⟨v^4− v⟩ which is suitable for describing DNA codes over this ring. Using the Gray map between F_4[v]/⟨v^4− v⟩ and F_4^4(or equivalently DNA 4-bases), we describe reversible DNA codes and reversible-complement DNA codes over this ring.

EXTENSION OF THE REGIME METHOD TO GROUP DECISION-MAKING IN A Q-RUNG ORTHOPAIR FUZZY ENVIRONMENT
YOUNOUSSA SARE, ZOÏNABO SAVADOGO, ELISEE GOUBA
q-Rung orthopair fuzzy sets (qROFS) constitute a robust extension of Intuitionistic Fuzzy Sets
(IFS) and Pythagorean Fuzzy Sets (PyFS). They provide an advanced framework for handling complex
information in an uncertain environment. The REGIME method is an MCDM approach used to provide a
definitive ranking of alternatives. In the literature(...)
