Constant curvature (2+1)-spacetimes and projective structures
Séminaire de théorie spectrale et géométrie, Volume 23 (2004-2005), pp. 9-48.

Nous illustrons une classification des espace-temps (2+1) globalement hyperboliques a courboure constant, en terms de certaines structures projectives complexes portées par les surfaces de niveau de leur temps cosmologique canonique. Ceci derive d’une theorie des rotations de Wick canoniques, developpée en collaboration avec Riccardo Benedetti [6], qui sera egalement brievement illustrée.
