This study deals with an optimal control problem subject to a stochas- tic elliptic equation with Dirichlet boundary condition and in which the state process is regular on a stochastic Hilbert space. We prove the ex- istence and uniqueness of the [...]
This paper provides a method for an optimal and equitable schedule of public load shedding on any time interval and any number of sectors. By combining dynamic programming and knapsack techniques, the method gives a schedule that iterates over part [...]
A model that takes into account multi-mutation and drug resistance in a case of sim- ple immune system and immune-suppression caused by drug resistant tumor cells is proposed. Since methods for revising therapeutic approaches (immunotherapy and ch [...]
Par un choix mathématique inspiré de l’histoire des mathématiques, nous avons montré l’utilité des nombres dans l’introduction du vecteur en classe de 4 e étant entendu que les nombres ont joué un rôle important dans la construction du concept. Pou [...]

Recently in [1, 2], Bromideh introduced the Kullback-Leibler Divergence (KLD) test statistic in discriminating between two models. It was found that the ratio minimized Kullback-Leibler divergence (RMKLD) works better than the ratio of maximized l [...]

We study the volume growth function of geodesic spheres in the universal Riemannian covering of a compact manifold of hyperbolic type. Furthermore, we investigate the growth rate of closed geodesics in compact manifolds of hyperbolic type [...]
Let (M, g) be a compact Riemannian manifold of hyperbolic type and X be its universal Riemannian covering. We study in this paper, the growth function of the geodesic balls of X. We show that the critical exponent of the group of deck transformation [...]
Let ( M , F ) be a compact Finsler manifold of hyperbolic type, and M F be its universal Finsle- rian covering. In this paper we show that the growth function of the volume of geodesic balls of M F is of purely exponential type. [...]
We study Weyl structures on lightlike hypersurfaces endowed with a conformal structure of certain type and specific screen distribution: the Weyl screen structures. We investigate various differential geometric properties of Einstein–Weyl screen st [...]
The Modified Chaplygin Gas (MCG) model belongs to the class of a unified models of dark energy (DE) and dark matter (DM). It is characterized by an equation of state (EoS) p c = B ρ − A / ρ α , where the case B = 0 corresponds to the Generalized Ch [...]
