Ground states of a Klein-Gordon field with Robin boundary conditions in global anti-de Sitter spacetime

Claudio Dappiaggi, Hugo Ferreira, Alessio Marta

We consider a real, massive scalar field both on the $n$-dimensional anti--de Sitter (AdS${}_n$) spacetime and on its universal cover CAdS${}_n$. In the second scenario, we extend the…
