Janus Deformation of de Sitter Space and Transitions in Gravitational Algebras

Dongsu Bak, Chanju Kim, Sang-Heon Yi

We consider a time-dependent $\mathcal{O}(1/G)$ deformation of pure de Sitter (dS) space in dS gravity coupled to a massless scalar field. It is the dS counterpart of the AdS Janus…
