Tachyons in de Sitter space and analytical continuation from dS/CFT to AdS/CFT
M. Cadoni, P. Carta
We discuss analytic continuation from d-dimensional Lorentzian de Sitter (dS) to d-dimensional Lorentzian anti-de Sitter (AdS) spacetime. We show that AdS, with opp…
Two-dimensional dS/CFT correspondence
M. Cadoni, P. Carta, M. Cavaglia' +1
We investigate de Sitter/conformal field theory (dS/CFT) correspondence in two dimensions. We define the conserved mass of de Sitter spacetime and formulate the correspondence alon…
Quantum dilaton gravity as a linear dilaton conformal field theory
M. Cadoni, P. Carta, S. Mignemi
A model of matter-coupled gravity in two dimensions is quantized. The crucial requirement for performing the quantization is the vanishing of the conformal anomaly, which is achiev…
The Cardy-Verlinde formula for 2D gravity
M. Cadoni, P. Carta, S. Mignemi
We discuss the different bounds on entropy in the context of two-dimensional cosmology. We show that in order to obtain well definite bounds one has to use the scale symmetry of th…
Cosmology of the Jackiw-Teitelboim model
M. Cadoni, S. Mignemi
We investigate the cosmology of the two-dimensional Jackiw-Teitelboim model. Since the matter coupling is not defined uniquely, we consider two possible choices. The dilaton field…
