Para-Kähler Einstein metrics on homogeneous manifolds
Comptes Rendus. Mathématique, Volume 347 (2009) no. 1-2, pp. 69-72.

A para-Kähler structure on a manifold M is a pair (g,K) where g is a pseudo-Riemannian metric and K is a parallel field of skew-symmetric endomorphisms with K2=Id. We give a description of all invariant para-Kähler structures (g,K) on homogeneous manifolds M=G/H of semisimple Lie groups G.

Une structure para-Kählérienne sur une variété M est la donnée d'un paire (g,K), où g est une metrique pseudo-riemannienne et K est un champ parallel d'endomorphismes anti-symétriques qui satisfait K2=Id. On donne une description de toutes les structures para-Kählériennes invariantes (g,K) sur des variétés homogènes M=G/H, où G est un group de Lie semisimple.
