Derivations and Dimentionally Nilpotent Derivations in Lie Algebras
Abdoulaye DEMBEGA , Amidou KONKOBO, MOUSSA OUATTARA
In this paper, we first study derivations in non nilpotent Lie triple algebras. We determine the structure of derivation algebra according to whether it admits an idempotent or a pseudo-idempotent. We study the multiplicative structure of non nil dimensionally nilpotent Lie triple algebras. We show that when n=2 p+1 the adapted basis coincides(...)

Nonlinear parabolic capacity and renormalized solutions for PDEs with diffuse measure data and variable exponent
M. Abdellaoui, E. Azroul, S. Ouaro, U. Traoré
We extend the theory of capacity to generalized Sobolev spaces for the study of nonlinear parabolic equations. We introduce the definition and some properties of renormalized solutions and we show that diffuse measure can be decomposed in space and time. As consequence, we show the existence and uniqueness of renormalized solutions. The main t(...)

General Solution of Linear Partial Differential Equations Modeling Homogeneous diffusion-convection-reaction Problems with Cauchy Initial Condition
Minoungou Youssouf, Bagayogo Moussa, Youssouf Pare
In this paper, we propose the general solution of di usion-convection-reaction homogeneous problems with condition initial of Cauchy, using the SBA numerical method. This method is based on the combination of the Adomian Decompositional Method(ADM), the successive approximations method and the Picard principle.

Global dynamics of a seasonal mathematical model of schistosomiasis transmission with general incidence function
TRAORE Bakary, KOUTOU Ousmane, SANGARE Boureima
In this paper, we investigate a nonautonomous and an autonomous model of schistosomiasis transmission with a general incidence function. Firstly, we formulate the nonautonomous model by taking into account the effect of climate change on the transmission. Through rigorous analysis via theories and methods of dynamical systems, we show that the(...)

Mathematical model of malaria transmission dynamics with distributed delay and a wide class of nonlinear incidence rates
KOUTOU Ousmane, TRAORE Bakary, SANGARE Boureima
Generally, the infection process of most vector-borne diseases involves a latent period in both human hosts and vectors. With regards to other publications, Tian and Song have recently proposed an SIR-SI model to analyze the effects of the incubation period on a vector-borne disease with nonlinear transmission rate. But they were silent on the(...)
