Uniform Stability of Dynamic SICA HIV Transmission Models on Time Scales
Zahra Belarbi, Benaoumeur Bayour, Delfim F. M. Torres
We consider a SICA model for HIV transmission on time scales. We prove permanence of solutions and we derive sufficient conditions for the existence and uniform asymptotic stabilit…
Legendre curves on 3-dimensional -Manifolds
Gherici Beldjilali, Benaoumeur Bayour, Habib Bouzir
Legendre curves play a very important and special role in geometry and topology of almost contact manifolds.There are certain results known for Legendre curves in 3-dimensional nor…
On the Generalised Ricci Solitons and Sasakian Manifolds
Ahmed Mohammed Cherif, Kaddour Zegga, Gherici Beldjilali
In this note, we find a necessary condition on odd-dimensional Riemannian manifolds under which both of Sasakian structure and the generalised Ricci soliton equation are satisfied,…
First-principles investigation of half-metallic ferromagnetism of FeYSn (Y = Mn, Ti and V) Heusler alloys
M. Sayah, S. Zeffane, M. Mokhtari +4
In this paper, we use the first-principles calculations based on the density functional theory to investigate structural, electronic and magnetic properties of FeYSn with (Y…
On the p-biharmonic submanifolds and stress p-bienergy tensors
Khadidja Mouffoki, Ahmed Mohammed Cherif
In this paper, we consider p-biharmonic submanifolds of aspace form. We give the necessary and sufficient conditions for a submanifold to be p-biharmonic in a space form. We presen…
Prediction of electronic and half metallic properties of MnYSn (Y = Mo, Nb, Zr) Heusler alloys
S. Zeffane, M. Sayah, F. Dahmane +4
We investigate the structural, electronic and magnetic properties of the full Heusler compounds MnYSn (Y = Mo, Nb, Zr) by first-principles density functional theory using the g…
