Remote Nordic HET seminar: De Sitter Gravity

Speaker: Ruben Monten

Title: De Sitter Gravity

Abstract: I will discuss the interesting features of gravity in asymptotically de Sitter spacetimes and the extent to which holographic ideas can be used to describe them. Despite its mathematical similarity to the AdS/CFT correspondence, crucial new elements are needed to complete the dS gravitational Hilbert space. This approach has been most successful for a specific type of higher-spin quantum gravity, leading to an exact proposal. I will describe some properties and predictions of this model and conclude with lessons learned for dS gravity in general.
