Helix curves of the unit tangent bundle of a pseudo-Riemannian surface
Mohamed Tahar Kadaoui Abbassi, Khadija Boulagouaz
In this paper, we classify helix (spacelike, timelike and null) curves, directed by the geodesic flow vector field, on the (3-dimensional) unit tangent bundle of a pseudo-Riemannia…
On biharmonic functions on vector bundles
Mohamed Tahar Kadaoui Abbassi, Souhail Doua, Ibrahim Lakrini
This paper is devoted to the investigation of harmonic and biharmonic functions on vector bundles equipped with spherically symmetric metrics. We will study the biharmonicity of ve…
On point spectra of vector fields
Mohamed Tahar Kadaoui Abbassi, Ibrahim Lakrini
The aim of this paper is to investigate the point spectra of vector fields. We will define the point spectrum of a vector field and study some of its basic properties. In particula…
Quasi-linear elliptic equations with data in on a compact Riemannian manifold
E. Azroul, A. Abnoune, M. T. K. Abbassi
This work is dedicated to the study of quasi-linear elliptic problems with data, the simple model will be the next equation on a compact Riemannian manifold. $$-Δ_{…
Natural Ricci Solitons on tangent and unit tangent bundles
Mohamed Tahar Kadaoui Abbassi, Noura Amri
Considering pseudo-Riemannian -natural metrics on tangent bundles, we prove that the condition of being Ricci soliton is hereditary in the sense that a Ricci soliton structure o…
Harmonic sections of tangent bundles equipped with Riemannian -natural metrics
M. T. K. Abbassi, G. Calvaruso, D. Perrone
Let be a Riemannian manifold. When is compact and the tangent bundle is equipped with the Sasaki metric , the only vector fields which define harmonic maps fr…
