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(...)

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(...)

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
