A Benchmarck of Filters with non-local Models for Denoising Corrupted Image
Satafa SANOGO OK David Urbain TRAORE
Dans ce travail, nous étudions des méthodes de restauration d’images corrompues en utilisant des modèles non locaux basés sur le laplacien à exposant variable. Nous traitons des images soumises au bruit de Cauchy ainsi que de celles dégradées par le bruit de Poisson. Ces problèmes de débruitage d’images sont formulés comme des problèmes d’opti(...)

Analysis and optimal control of a fractional-order model of a vector-borne disease
Ali Traoré; Rosaire Ouedraogo; Hamadoum Dicko
In this paper, a fractional-order model has been developed to study the transmission dynamics of a vector-borne disease. The use of fractional calculus, particularly through the Caputo derivative, provides a mathematical framework that accounts for memory effects and long-term dynamics often observed in vector-borne diseases. The difference be(...)

ROSELLE POLYNOMIALS AND THEIR q-ANALOGUE
Mamy Laingo Nomenjanahary Rakotoarison, Joël Kabore, Fanja Rakotondrajao, Gérard Kientega, Dimbiniaina Ratovilebamboavison
In this paper, we establish relations defining the coefficients of Roselle polynomials and give their combinatorial interpretation. Introducing the non-ascending permutations, we determine the q-Roselle polynomials as well as their q-exponential generating.

Fourier multipliers and Sobolev spaces on homogeneous spaces related to Gelfand pairs
Yaogan Mensah, Marie Francoise Ouedraogo
Let G be a locally compact Hausdorff group and let K be a compact subgroup of G such that (G,K) is a Gelfand pair. This paper is devoted to the study of Fourier multipliers and Sobolev spaces on the homogeneous space G/K. The Fourier multipliers and the Sobolev spaces on G/K are built from a vector-valued Fourier transformation related to unit(...)

Asymptotic behavior of a vector-host disease model with piecewise-smooth treatment
Issoufou Zoré, Boureima Ouedraogo, Ali Traoré
In this paper, we analyze a vector-host epidemic model with a piecewise-smooth treatment rate.The
use of piecewise-smooth treatment depicts the limited medical resource situation in the community. The treatment
increases linearly with infective population until the treatment capacity is reached, after which constant treatment(i.e
maximum tr(...)

Assessing the potential impact of the RTS, S/ASO1 vaccine on malaria burden in Benin: a mathematical modelling approach
Gouvidé Jean Gbaguidi, Mor Absa Loum, Lucien Diégane Gning, Aboudou Karime Tahiho, Elhadj Marouf Diallo, Ousmane Koutou, Andre Dembélé, Nikita Topanou & Guillaume K. Ketoh
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(...)

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(...)

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(...)

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(...)
