Complex Generalized Killing Spinors on Riemannian Spin manifolds
Nadine Große, Roger Nakad
In this paper, we extend the study of generalized Killing spinors on Riemannian Spin manifolds started by Moroianu and Herzlich to complex Killing functions. We prove that such…

Riemannian foliations with parallel or harmonic basic forms
Fida EL Chami, Georges Habib, Roger Nakad
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 curvatur…
