Pseudo lmost periodic solutions of infinite class in the α-norm under the light of measure theory
DJENDODE MBAINADJI, DJOKATA VOTSIA AND ISSA ZABSONRE
The aim of this work is to study weighted pseudo almost periodic functions with infinite delay via measure theory. Using the Banach fixed point theorem and the techniques of fractional powers of an operator, we establish the existence and uniqueness of pseudo almost periodic solutions in the alpha-norm of the infinite class for some functiona(...)

ON 3D COMPRESSIBLE PRIMITIVE EQUATIONS APPROXIMATION OF ANISOTROPIC NAVIER-STOKES EQUATIONS: RIGOROUS JUSTIFICATION
Jules Ouya , Arouna Ouédraogo
In this paper, we obtain the 3D compressible primitive equations approximation without gravity by taking the small aspect ratio limit to the Navier-Stokes equations in the isothermal case with gravity. The aspect ratio (the ratio of the depth to horizontal width) is a geometrical constraint in general large scale geophysical motions that the v(...)

ASYMPTOTIC EXPANSIONS FOR ELLIPTIC BOUNDARY VALUE PROBLEMS
KABORE Bruno, BELLA Boureima, LY Ibrahim
We propose an asymptotic solution related to a Cauchy problem for an elliptic
equation or system with data on a part of the boundary within solving operators
of Zaremba type mixed boundary problems.

STRUCTURAL STABILITY OF p(x)-LAPLACIAN KIND PROBLEMS WITH MAXIMAL MONOTONE GRAPHS AND NEUMANN TYPE BOUNDARY CONDITION
Kansié Kpè, Ouaro Stanislas
In this work, we study the convergence of a sequence of solutions of degenerate elliptic problems with variable coercivity and growth exponents. The functional setting involves Lebesgue and Sobolev spaces with variable ex- ponent which varies also with n

Resolution of the Standard Telegraph Equation by the Laplace-Adomian Method
MINOUNGOU Youssouf, BAGAYOGO Moussa ,PARE Youssouf
In this paper, we resarch the solution of the standard telegraph equation by the Laplace-Adomian method.
The Laplace-Adomian method is based on the combination of Laplace transform and the Adomian
decompositionnal method.

On a Compound Poisson Risk Model Perturbed by Brownian Motion with Variable Premium and Tail Dependence between Claims Amounts and Inter-Claim Time
Delwendé Abdoul-Kabir Kafando, Kiswendsida Mahamoudou Ouedraogo, Pierre Clovis Nitiema
Cet article examine un modèle de risque de Poisson composé perturbé par un mouvement brownien avec un prime variable et une dépendance entre les montants des réclamations et les temps entre les réclamations via la copule de Spearman. Le modèle présente deux classes de preneurs de police ayant des montants de réclamation différents, ce qui a de(...)

Existence and regularity of solutions in α-norm for some second order partial neutral functional differential equations with finite delay in Banach spaces
DJENDODE MBAINADJI, AL-HASSEM NAYAM AND ISSA ZABSONRE
In this paper, we investigate the regularity and existence of solutions in the α-norm for some second order partial
neutral functional differential equations with finite delay in Banach spaces. To do this, we use the cosine families theory and Schauder’s fixed point theorem to establish the existence of solutions and then we give some suffici(...)

MULTIPLICITY OF HETEROCLINIC SOLUTIONS FOR THE DISCRETE p(k)-LAPLACE KIRCHHOFF TYPE EQUATIONS WITH A PARAMETER
Moussa Brahim, Nyanquini Ismaël, Ouaro Stanislas
In this paper, we prove the existence of at least one and at least two nontrivial heteroclinic solutions for the discrete p(k)-Laplace Kirchhoff type equations depending on a parameter. The proof of our main result is based on a local minimum theorem for differentiable functionals due to Ricceri and on the mountain pass theorem of P. Pucci and(...)

Cet article présente une extension du modèle de risque de Poisson composé, intégrant une stratégie de paiement de dividendes avec une barrière constante. Le modèle inclut une dépendance entre les montants des réclamations et les intervalles entre réclamations, modélisée à l'aide de la copule de Spearman. Les résultats montrent que la dépendanc(...)

Cette étude repose sur le modèle de risque composite de Poisson, intégrant une stratégie de distribution des dividendes aux actionnaires. Un élément clé est l'introduction d'un seuil constant 'b', permettant de distinguer entre les petites réclamations et les événements majeurs ayant un impact significatif sur les réserves. De plus, le modèle(...)

NEUMANN PROBLEMS FOR NONLINEAR ELLIPTIC EQUATIONSINVOLVING VARIABLE EXPONENT AND MEASURE DATA
Mohamed Badr Benboubker, Stanislas Ouaro, Urbain Traore
This paper deals with the question of the existence of entropy solutions for the problem− div(a(x, u, ∇u) + φ(u)) + g(x, u, ∇u) = µ posed in an open bounded subset Ω of R^N with the homogeneous Neumann boundary condition (a(x, u, ∇u) + φ(u)) · η = 0. The functional setting involves Lebesgue and Sobolev spaces with variable exponent
