Gravitational Energy

---

We are generalising definitions of gravitational energy in assymptotically flat
spacetimes to spaces with more general asymptotic structures. Nelson Pinto Neto,
I.D.Soares and Ronaldo Rodrigues da Silva extended succesfully these definitions to
spaces asymptotically anti-de Sitter. Nelson Pinto Neto and Paulo Israel Trajtenberg
are now trying to generalise such results to compact objects that are asymptotically
Friedmann-Lemaitre-Robertson-Walker.
