Classical solutions for discrete potential boundary value problems with generalized Leray-Lions type operator and variable exponent
B.A. Kyelem, S. Ouaro, M. Zoungrana
In this article, we prove the existence of solutions for some discrete nonlinear difference equations subjected to a potential boundary type condition. We use a variational technique that relies on Szulkin’s critical point theory, which ensures the existence of solutions by ground state and mountain pass methods

Préambule aux opérateurs Fourier intégraux: les opérateurs pseudo-différentiels
Catherine Ducourtioux, Marie Françoise Ouedraogo
Dans ce travail, nous donnons une introduction aux opérateurs pseudodifférentiels en faisant une généralisation des opérateurs différentiels. Nous étendons ensuite ces opérations aux espaces de Sobolev puis aux espaces des distributions tempérées. Par la suite, nous étudions la continuité de ces opérateurs sur les espaces de Sobolev, ce qui pe(...)

On nilpotency in nonassociative algebras
Côme Jean Antoine Béré, Marie Françoise Ouedraogo, Moussa Ouattara
If a non associative algebra A is right nilpotent (resp. left nilpotent) of degree n, then it is strongly nilpotent of degree less or equal to 4n^2 − 2n + 1.

Controllability of nonlinear degenerate parabolic cascade systems
Mamadou BIRBA, Oumar TRAORE
This article studies of null controllability property of nonlinear coupled one dimensional degenerate parabolic equations. These equations form a cascade system, that is, the solution of the first equation acts as a control in the second equation and the control function acts only directly on the first equation. We prove positive null controll(...)

Multivalued Homogeneous Neumann Problem Involving Diffuse Measure Data and Variable Exponent
S. Ouaro, A. Ouedraogo and S. Soma
We study a nonlinear elliptic problem with homogeneous Neumann boundary condition, governed by a general Leray-Lions operator with variable expo- nents and Radon measure data which does not charge the sets of zero p(.)-capacity. We prove an existence and uniqueness result of weak solution.

Controllability in the α-norm of some impulsive differential equation with infinite delay in Banach spaces
Issa ZABSONRE
n this work, sufficient conditions for the controllability in the -norm of impulsive systems
with nonlocal conditions with infinite delay are established. We assume that the linear part generates a
compact analytic semigroup on a Banach space X, the delayed part is assumed to be continuous with

Modeling battery cells under discharge using kinetic and stochastic battery models
Ingemar Kaj, Victorien Konané
In this paper we review several approaches to mathematical modeling of simple battery cells and develop these ideas further with emphasis on charge recovery and the response behavior of batteries to given external load. We focus on models which use few parameters and basic battery data, rather than detailed reaction and material characteristic(...)

Pseudo almost periodic and Pseudo almost automorphic solutions of class r under the light of measure theory
Issa ZABSONRE, Hamidou TOURE
The aim of this work is to present new approach to study weighted pseudo almost periodic and automorphic functions using the measure theory. We present a new concept of weighted ergodic functions which is more general than the classical one. Then we establish many interesting results on the functional space of such functions. We study the exis(...)

Constacyclic codes over F_q + uF_q + vF_q + uvF_q
Joël Kabore, Mohammed E. Charkani
Let q be a prime power and Fq be a nite eld. In this paper, we study constacyclic
codes over the ring F_q + uF_q + vF_q + uvF_q, where u2 = u; v2 = v and uv = vu: We
characterized the generator polynomials of constacyclic codes and their duals using
some decomposition of this ring.
