Renormalisation in maximally symmetric spaces and semiclassical gravity in Anti-de Sitter spacetime

Benito A. Juárez-Aubry, Milton C. Mamani-Leqque

We obtain semiclassical gravity solutions in the Poincaré fundamental domain of $(3+1)$-dimensional Anti-de Sitter spacetime, PAdS${}_4$, with a (massive or massless) Klein-Gordon fi…
