Skew-Constacyclic Codes Over F_q [v]/ ‹ v^q -v ›
Joël Kabore, Alexandre Fotue-Tabue, Kenza Guenda, Mohammed E. Charkani
In this paper, we investigate the algebraic structure of the
non-chain ring F_q [v]/ ‹ v^q -v › , followed by the description of its
group automorphisms to get the algebraic structure of codes and their
dual over this ring. Further, we explore the algebraic structure of
skew-constacyclic codes by showing that their images by a linear Gray(...)

Statistical Modeling and Forecast of the Corona-Virus Disease (Covid-19) in Burkina Faso
VICTORIEN F. KONANE, Ali TRAORE
In this paper, we present and discuss a statistical modeling framework for the coronavirus COVID-19 epidemic in Burkina Faso. We give a detailed analysis of well-known models, the ARIMA and the Exponential Smoothing model.
The main purpose is to provide a prediction of the cumulative number of confirmed cases to help authorities to take bette(...)

Modeling the effects of contact tracing on COVID-19 transmission
Ali Traoré, Fourtoua Victorien Konané
In this paper, a mathematical model for COVID-19 that involves contact tracing is studied. The contact tracing-induced reproduction number Rq and equilibrium for the model are determined and stabilities are examined. The global stability results are achieved by constructing Lyapunov functions. The contact tracing-induced reproduction number Rq(...)

Mathematical analysis of mosquito population global dynamics using delayed-logistic growth
KOUTOU Ousmane, SANGARE Boureima, DIABATE Abou Bakari
Malaria is a major public health issue in many parts of the world, and the anopheles mosquitoes which drive
transmission are key targets for interventions. Consequently, a best understanding of mosquito populations
dynamics is necessary in the fight against the disease. Hence, in this paper we propose a delayed mathematical
model of the lif(...)

Primitive idempotents and constacyclic codes over finite chain rings
Mohammed Elhassani Charkani, Joël Kabore
Let R be a commutative local nite ring. In this paper, we construct the complete set of pairwise orthogonal primitive idempotents of R[X]/ where g is a regular polynomial in R[X]. We use this set to decompose
the ring R[X]/ and to give the structure of constacyclic codes over
nite chain rings. This allows us to describe generators of th(...)

SOME COMBINATORIAL PROPERTIES AND LYNDON FACTORIZATION OF THE PERIOD-DOUBLING WORD
K. Ernest Bognini, Idrissa Kaboré, Théodore Tapsoba
In this paper, we study some properties of finite factors of the period-doubling word. More precisely, we focus on the structure of its palindromes and establish its Lyndon factorization.

Pseudo almost automorphic solutions of class r in α-norm under the light of measure theory
Issa Zabsonre, Djendode Mbainadji
Using the spectral decomposition of the phase space developed in Adimy and co-authors, we present a new approach to study weighted pseudo almost automorphic functions in the α-norm using the measure theory.

Same decay rate of second order evolution equations with or without delay.
Gilbert Bayili ; Akram Ben Aissa; Serge Nicaise
We consider abstract second order evolution equations with unbounded feedback with delay. If the delay term is small enough, we rigorously prove the fact that the system with delay has the same decay rate than the one without delay. Some old and new results easily follow.

A global mathematical model of malaria transmission dynamics with structured mosquito population and temperature variations
TRAORE Bakary, KOUTOU Ousmane, SANGARE Boureima
In this paper, a mathematical model of malaria transmission which takes into account the four distinct mosquito metamorphic stages is presented. The model is formulated thanks to the coupling of two sub-models, namely the model of mosquito population and the model of malaria parasite transmission due to the interaction between mosquitoes and h(...)

CROSS AND SELF-DIFFUSION MATHEMATICAL MODEL WITH NONLINEAR FUNCTIONAL RESPONSE FOR PLANKTON DYNAMICS
HAMIDOU OUEDRAOGO, BOUREIMA SANGARE AND WENDKOUNI OUEDRAOGO
The aim of this paper is to show with a functional Beddington-DeAngelis response, that cross-diffusion plays an important role in the phenomenon of toxin-productionphytoplankton (TPP) in the dynamics of zooplankton and phytoplankton system. The
demonstration tools are mainly based on the theory of fixed point indices and analytical techniq(...)

Existence and regularity of solutions in α-norm for some partial functional integrodifferential equations in banach Spaces
Issa Zabsonre, Djendode Mbainadji
In this work, we study the existence and regularity of solutions in α-norm for some partial functional integrodifferential equations in Banach spaces. We suppose that the undelayed part admits a resolvent operator, the delayed part is assumed to be locally lipschitz. Firstly, we show the existence of mild solutions. Secondly, we give sufficien(...)

A mathematical model of malaria transmission dynamics with general incidence function and maturation delay in a periodic environment
TRAORE Bakary, KOUTOU Ousmane, SANGARE Boureima
In this paper, we investigate a mathematical model of malaria transmission dynamics with maturation delay of a vector population in a periodic environment. The incidence rate between vector and human hosts is modeled by a general nonlinear incidence function which satisfies a set of conditions. Thus, the model is formulated
as a system of re(...)

Existence and regularity of solutions for some nonlinear second order differential equation in banach spaces
Issa Zabsonre and Micailou Napo
In this work, we study the existence and regularity of solutions for some nonlinear second order differential equation. The delayed part is assumed to be locally lipschitz. Firstly, we show the existence of the mild solutions. Secondly, we give sufficiently conditions ensuring the existence of strict solutions.
