✦ Synopsis
Bochner's technique is applied to the study of timelike vectors fields on a Lorentzian manifold. In the compact case, a Lorentzian Bochner integral formula is obtained. As a consequence, compact Ricci flat Lorentzian manifolds admitting a timelike conformal vector field are classified. Both in the compact and non compact case, some obstructions to the existence of certain types of timelike vector fields are given.

In this paper we study the geodesical connectedness of Lorentzian manifolds. We consider a connected manifold M=M 0 \_R, where M 0 is a complete Riemannian manifold endowed with a Lorentzian metric g of splitting type. We prove that, under suitable hypotheses on the coefficients of the metric g, M i
In this paper we characterize the convexity of the boundary ∂S of a static (standard) Lorentzian manifold S in terms of Jacobi metrics. From this result, we also obtain: (1) a characterization of the convexity of ∂S computable from its "spacelike" part, (2) the equivalence between the variational an
We consider the Dirac operator D of a Lorentzian spin manifold of even dimension n > 4. We prove that the square D 2 of the Dirac operator on plane wave manifolds and the shifted operator D 2 -K on Lorentzian space forms of constant sectional curvature K are of Huygens type. Furthermore, we study th
