dS Metamorphosis
Dionysios Anninos, Chiara Baracco, Vasileios A. Letsios +1
We study the Euclidean path integral of higher spin gravity on . Based on a one-loop analysis, we are led to a gluing formula expressing the path integral in terms of an…
dS Supergravity
Dionysios Anninos, Pietro Benetti Genolini, Beatrix Mühlmann
We construct two-dimensional supergravity theories endowed with a positive cosmological constant, that admit de Sitter vacua. We consider the cases of as well as $\…
The two-sphere partition function in two-dimensional quantum gravity
Dionysios Anninos, Teresa Bautista, Beatrix Mühlmann
We study the Euclidean path integral of two-dimensional quantum gravity with positive cosmological constant coupled to conformal matter with large and positive central charge. The…
Remarks on 2D quantum cosmology
Dionysios Anninos, Chiara Baracco, Beatrix Mühlmann
We consider two-dimensional quantum gravity endowed with a positive cosmological constant and coupled to a conformal field theory of large and positive central charge. We study cos…
