ON UNIQUENESS OF LOCAL ENTROPY SOLUTION OF A CONVECTION-DIFFUSION TYPE INTEGRO-DIFFERENTIAL EQUATION
MOHAMED BANCE and SAFIMBA SOMA
We study the uniqueness of entropy solution for a class of triply
nonlinear parabolic integro-differential equations of the form
∂t k ∗(j(v)−j(v0)) −∇· a(x, ∇ϕ(v)) + F (ϕ(v)) = f
in a bounded domain with homogeneous Dirichlet boundary conditions. The
source term f belongs to L1 and the memory term k ∗(j(v)−j(v0)) introduces
a nonlocal depe(...)

Implementation of a Voting Method Based on Mean-Deviation Evaluation for a Large-Scale Election
Hadarou Yiogo, Zoïnabo Savadogo
Today, many countries around the world, particularly in Africa, are experiencing post-election difficulties due to unexpected
election results. This sometimes provokes protests and revolt among the population. To overcome this major problem, several
voting systems have been developed in the literature, but some of them are not lacking in s(...)

Mathematical modeling of bi-mode transmission of hepatitis B with media coverage
Abdoul Aziz Gansonré, Adama Ouédraogo & Ousmane Koutou
This paper presents a bi-mode transmission model for hepatitis B, focusing on two primary transmission routes:
blood transfusion and excessive intravenous drug use. We constructed the model and conducted a mathematical analysis,
including the calculation of the basic reproduction number using the next-generation matrix method and identifying(...)

Rational stabilization of the multidimensional wave equation with dynamical control and time-varying delay
Désiré SABA, Innocent OUEDRAOGO, Gilbert BAYILI
We consider the multidimensional wave equation with a time-varying delay term in the dynamical control. Under suitable assumptions, we show the well posedness of the problem. These results are obtained by using semi-group theory. Using direct computations, through the multiplier method, the rational energy decay rate of the system will be give(...)

A THEORETICAL ASSESSMENT OF THE EFFECTS OF HOSPITAL RESOURCES ON A HOST-VECTOR DISEASE
ROSAIRE OUEDRAOGO, ALI TRAORE, HAMADOUM DICKO
This paper provides a mathematical analysis of a host vectors disease model with the influence of available hospital resources. We derive the basic reproduction number Rh0 of the model. We prove the existence of a unique disease-free equilibrium, which is stable when the basic reproduction number Rh0 is less than 1, indicating that the disease(...)

MEAN (µ, ν)-PSEUDO ALMOST PERIODIC SOLUTIONS OF CLASS r UNDER THE ANGLE OF MEASURE THEORY TO SOME STOCHASTIC EVOLUTION EQUATIONS
Victorien Fourtoua Konane, Bernard Balma
The paper introduces and studies the concept of mean
(µ, ν)-pseudo almost periodic solution of class r for stochastic processes
using the measure theory. We use (µ, ν)-ergodic process to define the spaces
of (µ, ν)-pseudo almost periodic processes of class r in the mean sense. We
also present many interesting results on this spaces, such a(...)

A Circular Spatial-diffusion Mathematical Model to Analysis Hopf-Turing Bifurcation in Plankton Population Under the Toxin Control Variation in 2D
Hamidou Ouedraogo , Wendkouni Ouedraogo, Desire Ouedraogo, Boureima Sangare
In a mathematical model of a system with two reaction-diffusion equations with Neumann-Dirichlet boundary
conditions, we formulated zooplankton-phytoplankton in the aquatic environment on the circular domain. The attention has been
focused on the toxin producing role of the space in explaining heterogeneity, the distribution of the species a(...)

Existence and regularity of solutions in α-norm for Some second order partial neutral functional Differential equations with finite
DJENDODE MBAINADJI, SYLVAIN KOUMLA AND ISSA ZABSONRE
The purpose of this work is to investigate the existence and regularity of solutions in the α-norm for some second order partial neutral functional differential equations in Banach
spaces with finite delay using fractional -power and the theory of the cosine family. As result, we obtain a generalization of work of Herman R. Henriquez et al.(...)

ON SOME FRACTIONAL MODELS OF LOTKA-VOLTERRA
Traoré André, Francis Bassono and Kamate Adama
In this paper, we study two fractional models of Lotka-Volterra.
We begin by recalling the fundamental notions of fractional analysis.
Then we proceed in a second step to give the description of the
Adomian method and we finish our work with the description and
resolution of some fractional models of Lotka-Volterra. In the first

Mellin-SBA Method for Solving Nonliear Partial Differential Equations
Traoré André, Kamate Adama and Francis Bassono
In this paper, we present a new numerical method for solving nonlinear differential and partial differential
equations. This method is the Mellin-SBA method. In the first part, we describe the SBA and Mellin-SBA
methods. The second part is devoted to solving two nonlinear problems by the Mellin-SBA method.

Cholera invasion speed and the intervention strength
Komi Afassinou, Ousmane Koutou, Narcisse Roland Loufouma Makala
We formulate a mathematical model which captures the essential dynamics of cholera infection transmission. Control interventions such as vaccination program and environmental sanitation service are incorporated to analyse the impact of both interventions on the infection dynamics. The qualitative and numerical analyses of the model are carried(...)

Study of a Mild Solution of a Stochastic Integrodifferential Equation with Non-lipschitzian Coefficients in a Complex Hilbert Space
Wahabo BAGUIAN, Victorien F. KONANE and Claude YAMEOGO
In this work we consider a system of stochastic integrodifferential equations in a complex Hilbert space. We first establish the existence and uniqueness of mild solutions for our equation (1) under non-Lipschitz conditions. Then we show under certain assumptions that the mild solution found is asymptotically stable in mean order n. We obtain(...)

In this article, we study a class of convective diffusive elliptic problem with Dirichlet

CONTROLLABILITY OF A STOCHASTIC MODEL OF LYMPHATIC FILARIASIS
Ragnimwendé SAWADOGO, Victorien KONANE
This paper analyzes the controllability of a stochastic model of lymphatic filariasis. Like other
diseases, the spread of lymphatic filariasis is subject to a degree of randomness due to fluctuations in
the natural environment. This provides an opportunity to formulate a mathematical model of lymphatic
filariasis that accounts for as much e(...)
