2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/52772I review some interesting features of massive gravity in two maximally symmetric backgrounds: Anti de Sitter space and Minkowski space.

Here, I point out the problems encountered in trying to find such completion, and possible mechanisms to overcome them.8 pages, to appear in the proceedings of "Deserfest: A celebration of the life and works of Stanley Deser," University of Michigan, Ann Arbor, April 3-5, 2004High Energy Physics - Theorytext
