The objective of this study is to report three cases of paraneoplastic or ectopic Cushing syndrome, which is a rare phenomenon of the adrenocorticotropic hormone (ACTH)-dependent Cushing syndrome. Three cases are reported in respect of clinical prese

This paper is devoted to the classification of 4-dimensional Riemannian spin manifolds carrying skew Killing spinors. A skew Killing spinor $$\psi $$ ψ is a spinor that satisfies the equation $$\nabla _X\psi =AX\cdot \psi $$ ∇ X ψ = A X · ψ wit

International audience; We characterise those complete Kähler manifolds supporting a nonconstant real-valued function with critical points whose Hessian is nonnegative, complex linear, has pointwise two eigenvalues and whose gradient is a Hessian-ei

Riemannian foliations with parallel or harmonic basic forms

Autor: Fida El Chami, Roger Nakad, Georges Habib

Publikováno v: Archivum Mathematicum. :51-65

In this paper, we consider a Riemannian foliation whose normal bundle carries a parallel or harmonic basic form. We estimate the norm of the O'Neill tensor in terms of the curvature data of the whole manifold. Some examples are then given.

Eigenvalue bounds of the Robin Laplacian with magnetic field

Autor: Georges Habib, Ayman Kachmar

On a compact Riemannian manifold M with boundary, we give an estimate for the eigenvalues $$(\lambda _k(\tau ,\alpha ))_k$$ of the magnetic Laplacian with Robin boundary conditions. Here, $$\tau $$ is a positive number that defines the Robin conditio
