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 gravity with an invariant energy scale and arbitrary dilaton potential

S. Mignemi

We investigate a model of two-dimensional gravity with arbitrary scalar potential obtained by gauging a deformation of de Sitter or more general algebras, which accounts for the ex…

Two-dimensional gravity with an invariant energy scale

S. Mignemi

We investigate the gauging of a two-dimensional deformation of the Poincare algebra, which accounts for the existence of an invariant energy scale. The model describes 2D dilaton g…

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…
