Liouville gravity from Einstein gravity
نویسنده
چکیده
We show that Liouville gravity arises as the limit of pure Einstein gravity in 2+ ε dimensions as ε goes to zero, provided Newton’s constant scales with ε. Our procedure – spherical reduction, dualization, limit, dualizing back – passes several consistency tests: geometric properties, interactions with matter and the Bekenstein-Hawking entropy are as expected from Einstein gravity.

Gravity in 2 + ǫ Dimensions
Quantum theory of dilaton gravity is studied in 2+ ǫ dimensions. Divergences are computed and renormalized at one-loop order. The mixing between the Liouville field and the dilaton field eliminates 1/ǫ singularity in the Liouville-dilaton propagator. This smooth behavior of the dilaton gravity theory in the ǫ → 0 limit solves the oversubtraction problem which afflicted the higher orders of the ...
متن کاملThe Asymptotic Dynamics of de Sitter Gravity in three Dimensions
We show that the asymptotic dynamics of three-dimensional gravity with positive cosmological constant is described by Euclidean Liouville theory. This provides an explicit example of a correspondence between de Sitter gravity and conformal field theories. In the case at hand, this correspondence is established by formulating Einstein gravity with positive cosmological constant in three dimensio...

In this paper we consider the action of higher derivative gravity up to the second order terms in the scalars made from the Ricci scalar, Ricci and Riemann tensors. We use the Bach- Lanczos identity of the Weyl tensor in four dimensions and show that the solutions of 4-dimensional Einstein equations with cosmological constant term in vacuum, which are known as Einstein metrics, satisfy the fie...
متن کاملGravity Coupled to a Nonlinear Sigma Model in 2 + ǫ Dimensions
Quantum theory of dilaton gravity coupled to a nonlinear sigma model with a maximally symmetric target space is studied in 2 + ǫ dimensions. The ultraviolet stable fixed point for the curvature of the nonlinear sigma model demands a new fixed point theory for the dilaton coupling function. The fixed point of the dilaton coupling is a saddle point similarly to the previous case of the flat targe...
متن کاملInterpretation of Black Hole Entropy
In this paper we will compute the entropy of a Schwarzschild black hole by finding a classical central charge of the Virasoro algebra of a liouville theory and using the Cardy formula. This is done by performing a dimensional reduction of the Einstein-Hilbert action with the Ansatz of spherical symmetry and writing the metric in conformally flat form. We obtain two coupled field equations and u...
