Contact pair structures and associated metrics
G. Bande, A. Hadjar
We introduce the notion of contact pair structure and the corresponding associated metrics, in the same spirit of the geometry of almost contact structures. We prove that, with res…

On normal contact pairs
G. Bande, A. Hadjar
We consider manifolds endowed with a contact pair structure. To such a structure are naturally associated two almost complex structures. If they are both integrable, we call the st…

Contact Pairs
Gianluca Bande, Amine Hadjar
We introduce a new geometric structure on differentiable manifolds. A \textit{Contact} \textit{Pair}on a manifold is a pair of Pfaffian forms of constant classes $2k+1…
