Construction of a Class of Copula Using the Finite Difference Method
Remi Guillaume Bagré, Frédéric Béré, and Vini Yves Bernadin Loyara
The definition of a copula function and the study of its properties are at the same time not obvious tasks, as there is no general method for constructing them. In this paper, we present a method that allows us to obtain a class of copula as a solution to a boundary value problem. For this, we use the finite difference method which is a common(...)

Mathematical modelling of the evolution dynamics of the coronavirus disease 2019 (COVID-19) in Burkina Faso.
A. Guiro, B. Koné, S. Ouaro
In this paper, we develop a compartmental model of the COVID-19 epidemic in Burkina Faso by taking into account the compartments of hospitalized, severely hospitalized patients and dead persons. The model exhibits the traditional threshold behavior. We prove that when the basic reproduction number is less than one, the disease-free equilibrium(...)

Weak solutions for anisotropic nonlinear discrete Dirichlet boundary value problems in a two-dimensional Hilbert space
I. Ibrango, B. Koné, A. Guiro, S. Ouaro
Using a minimization method we study the existence of weak solutions for a family of nonlinear discrete Dirichlet boundary value problems where the solution lies in a discrete (T1×T2)-Hilbert space. The originality of this work is the study done on a two-dimensional Hilbert space

A mathematical analysis of Hopf-bifurcation in a prey-predator model with nonlinear functional response
Savadogo, Assane; Sangaré, Boureima; Ouedraogo, Hamidou
n this paper, our aim is mathematical analysis and numerical simulation of a
prey-predator model to describe the effect of predation between prey and predator
with nonlinear functional response. First, we develop results concerning the
boundedness, the existence and uniqueness of the solution. Furthermore, the
Lyapunov principle and the Ro(...)

Stepanov-like pseudo almost periodic solutions of infinite class under the light of measure theory
Issa ZABSONRE, Djokata VOTSIA
The aim of this work is to study weighted Stepanov-like pseudo almost periodic functions with infinite delay 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 also study the exist(...)

Solving Some Derivative Equations Fractional Order Nonlinear Partials Using the Some Blaise Abbo Method
Abdoul wassiha NEBIE, Frédéric BERE, Bakari ABBO3, Youssouf PARE
In this paper, we propose the solution of some nonlinear partial differential equations of fractional order that modeled
diffusion, convection and reaction problems. For the solution of these equations we will use the SBA method which is a
method based on the combination of the Adomian Decomposition Method (ADM), the Picard’s principle and t(...)

Markov Modeling of Battery Cell Behavior Taking in account Pulsed Discharge Recovery
Konane, V. F.
In this work, we modeled the behavior of a battery. After having formulated a Markovian model, we evaluated the delivered capacity as well as the gained capacity. We, likewise, evaluated the mean number of pulses and studied the asymptotic behavior and the variance of this mean number. As a last resort, we introduced an extension of the Markov(...)
