The Beta- flatness Condition in CR Spheres Multiplicity Results
Najoua Gamara, Boutheina Hafassa, Akrem Makni
We give multiplicity results for the problem of prescribing the scalar curvature on Cauchy- Riemann spheres under Beta-flatness condition. To give a lower bound for the number of s…

Torsional Rigidity on Compact Riemannian Manifolds with lower Ricci Curvature Bounds
Najoua Gamara, Abdelhalim Hasnaoui, Akrem Makni
In this article we prove a reverse Hölder inequality for the fundamental eigenfunction of the Dirichlet problem on domains of a compact Riemannian manifold with lower Ricci curvatu…
