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(...)

Combinaison des méthodes EVAMIX et VMAVA+ et application au choix d’un type de volaille pour une ferme
Zoïnabo SAVADOGO, Université Joseph KI-ZERBO, UFR/SEA,Ouagadougou,Burkina Faso Hadarou Yiogo, Université Joseph KI-ZERBO, LANIBIO,UFR/SEA, Ouagadougou, Burkina Faso
L’aide à la décision constitue un outil indispensable dans le processus de prise de décision.
Les différentes méthodes existantes ont prouvé leurs efficacités dans la résolution des
problèmes d’aide à la décision mais certaines rencontrent des difficultés dans la résolution
de certains problèmes. L’objectif de ce travail est de proposer es(...)

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(...)

INFINITE MATRIX ASSOCIATED TO SEQUENCES
Mamy Laingo Nomenjanahary Rakotoarison, Dimbiniaina Ratovilebamboavison, Joël Kabore, Gérard Kientega, Fanja Rakotondrajao
In this paper, we study the Euler-Seidel matrices with coefficients and determine the associated Riordan matrix to a given matrix, if it does exist. Computation of the generating function of the final sequence is established by the associated Riordan matrix.

On the study of cellular automata on modulo-recurrent words
Moussa Barro, K. Ernest Bognini and Boucaré Kientéga
In this paper, we study some class of cellular automata (CA) preserving modulo-recursive, stability by reflection and richness called stable cellular automata (SCA). After applying these automata on Sturmian words, we establish some combinatorial properties of these new words. Next, the classical and palindromic complexity functions of these w(...)

Media campaigns, early diagnosis, isolation and treatment on bacterial meningitis outbreak prevention: A modeling study
Ousmane Koutou, Wendkouni Ouedraogo, Hamidou Ouedraogo, Komi Afassinou, Abou Bakari Diabate
Bacterial meningitis is a severe infection affecting the protective membranes of the brain and spinal cord, with rapidly worsening symptoms that can lead to life-threatening complications. This study presents an autonomous deterministic epidemic model, SIaIsMRS, to explore the dynamics of bacterial meningitis in a community implementing contro(...)

Analysis of a nonlinear boundary value problem with p-Laplacian operator and Robin-type nonlinear boundary condition
MAMADOU BIRBA, AMIDOU TRAORE AND OUMAR TRAORE
In this paper, we study the existence of a solution of a nonlinear system involving the p-Laplace operator, a reaction
of the form μ|z|q z, a general nonlinearity f (z) with nonhomogeneous and nonlinear Robin-type boundary conditions. We
prove the existence and uniqueness of a weak solution to this problem by reformulating the system and app(...)

Privileged Complexity of the ternary Thue-Morse word
Boucaré Kientéga, K. Ernest Bognini and Moussa Barro
In this paper, we focus on a new type of complexity of infinite words called privileged complexity. We apply this concept to the ternary Thue-Morse word. First, we present properties of the return words in the ternary Thue-Morse word. Then, we study the privileged words of this infinite word. Finally, we derive a recursive formula that allows(...)
