Boundedness of Nonregular Pseudo-differential Operators and Their Adjoints on Variable Exponent Besov-Morrey Spaces
Mohamed Congo, Marie Françoise Ouedraogo
This paper deal with the boundedness property of non regular pseudo-differential operators a(x, D) and their adjoints a(x, D)∗ on variable exponent BM spaces. For this purpose, given such an operator, we use the technique of decomposition of its symbol into elementary symbols already used in other spaces.

Sélection de la meilleure variété de papaye par une méthode d’aide à la décision
Sougoursi Jean Yves ZARE, Z𝒐𝒊𝒏𝒂𝒃𝒐 SAVADOGO
Le secteur agricole en général représente une part importante de l’économie du Burkina Faso.
Ce secteur à lui seul contribue à près de 35% du PIB. L’arboriculture y occupe une place de
choix. Cependant, ce secteur souffre d’une faible productivité due entre autres à la non maitrise
des techniques de production et de sélection de semenc(...)

Choix d'un vaccin au Burkina Faso contre le covid- 19 par une méthode d'Aide à la Decision
Sougoursi Jean Yves ZARE , Z𝑜𝚤𝑛𝑎𝑏𝑜 SAVADOGO
Alors que de nombreux pays continuent de lutter contre les nouvelles infections
causées par le coronavirus 2019 (COVID-19), la mise au point d'un vaccin s'est
accélérée afin d'obtenir une immunité contre le virus et de stopper la transmission.
Cependant, certains pays ont encore un faible taux de vaccination notamment les
pays africain(...)

Application of the Some Blaise Abbo (SBA) Method to Solving the Time-fractional Schrödinger Equation and Comparison with the Homotopy Perturbation Method
Joseph Bonazebi Yindoula a, Yanick Alain Servais Wellot a, Bamogo Hamadou, Francis Bassono b and Youssouf Paré
We have solved the Schrödinger equation with the HPM method and the SBA method. We have
noticed that with these two methods we find the same result.

Renormalized solutions for a p(⋅)-Laplacian equation with Neumann nonhomogeneous boundary condition involving diffuse measure data and variable exponent
M.B. Benboubker, E. Nassouri, S. Ouaro, U. Traoré
In this paper we prove the existence of at least one renormalized solution for the p(x)-Laplacian equation associated with a maximal monotone operator and Radon measure data. The functional setting involves Sobolev spaces with variable exponent W1,p(⋅)(Ω)

An Existence Result in alpha-norm for Impulsive Functional Differential Equations with Variable Times
Issa Zabsonre
The dynamics of evolving processes is often subjected to abrupt changes such as shocks, harvesting, and natural
disasters. Often these short-term perturbations are treated as having acted instantaneously or in the form of “impulses.” In fact, there are many processes and phenomena in the real world, which are subjected during their developmen(...)

Indirect boundary stabilization with distributed delay of coupled multi-dimensional wave equations.
Roland Silga, Bila Adolphe Kyelem, Gilbert Bayili
In this article, our main concern is the study of the e ect of a distributed timedelay in boundary stabilization of a strongly coupled multi-dimensional wave equations. We will establish that the system with time-delay inherits the same exponential decay rate from the corresponding one without delay.

Stabilization of the schrödinger equation with distributed delay in boundary feedback
ROLAND SILGA, GILBERT BAYILI AND ISSA ZABSONRE
In this paper, we investigate the effect of a distributed time-delay in boundary stabilization of the Schrödinger equation. Under suitable assumptions, we establish sufficient conditions on the distributed delay term that guarantee the exponential stability of the solution using the frequency domain approach and a duality argument.

Local existence and regularity of solutions in alpha-norm for some partial functional integrodifferential equations in Banach spaces
Djendode Mbainadji and Issa Zabsonre
By using the resolvent operator theory in the sense given by Grimmer in [1], we prove the existence and regularity of solutions in α-norm for some partial functional integrodifferential equations in Banach spaces. We firstly show the existence of the mild solutions and give some conditions for the existence of strict solutions.

Square-mean pseudo almost periodic solutions of class r under the light of measure theory
MOHAMADO KIEMA AND ISSA ZABSONRE
The aim of this work is to present new concept of square-mean pseudo almost periodic of class r using the measure theory. We use the ergodic process to define the spaces of pseudo almost periodic processes of class r in the square-mean sense. We present many interesting results on those spaces like completeness and composition theorems

A mathematical analysis of prey-predator population dynamics in the presence of an SIS infectious disease
Savadogo, Assane; Sangaré, Boureima; Ouedraogo, Hamidou
n this paper, we propose and analyze a detailed mathematical model describing the dynamics of a preypredator model under the influence of an SIS infectious disease by using nonlinear differential
equations. We use the functional response of ratio-dependent Michaelis-Menten type to describe the
predation strategy. In the presence of the di(...)
