Resumen de Lorentz C12- manifolds

Adel Delloum, Gherici Beldjilali

• The object of the present paper is to study C12-structures on a manifold with Lorentzian metric. We focus here on Lorentzian C12-structures, emphasizing their relationship and analogies with respect to the Riemannian case. Several interesting results are obtained. Next, we study Ricci solitons in Lorentzian C12-manifolds.
