The renormalized volume of hyperbolic manifolds is a quantity motivated by the AdS/CFT correspondence of string theory and computed via a certain regularization procedure. The main aim of the present paper is to elucidate its geometrical meaning. We use another regularization procedure based on surfaces equidistant to a given convex surface ∂N. The renormalized volume computed via this procedure is equal to what we call the W-volume of the convex region N given by the usual volume of N minus… 
Constant Gaussian curvature foliations and Schläfli formulas of hyperbolic 3-manifolds
We study the geometry of the foliation by constant Gaussian curvature surfaces $(\Sigma_k)_k$ of a hyperbolic end, and how it relates to the structures of its boundary at infinity and of its pleated
The Weil-Petersson metric and the renormalized volume of hyperbolic 3-manifolds
We survey the renormalized volume of hyperbolic 3-manifolds, as a tool for Teichmuller theory, using simple differential geometry arguments to recover results sometimes first achieved by other means.
Renormalized Area and Properly Embedded Minimal Surfaces in Hyperbolic 3-Manifolds
We study the renormalized area functional $${\mathcal{A}}$$ in the AdS/CFT correspondence, specifically for properly embedded minimal surfaces in convex cocompact hyperbolic 3-manifolds (and somewhat

AbstractWe study the volume of maximal globally hyperbolic Anti-de Sitter manifolds containing a closed orientable Cauchy surface S, in relation to some geometric invariants depending only on the two
Infinitesimal rigidity of convex surfaces through the second derivative of the Hilbert-Einstein functional II: Smooth case
The paper is centered around a new proof of the infinitesimal rigidity of smooth closed surfaces with everywhere positive Gauss curvature. We use a reformulation that replaces deformation of an
Renormalized volume and the evolution of APEs
Abstract We study the evolution of the renormalized volume functional for even-dimensional asymptotically Poincaré-Einstein metrics (M, g) under normalized Ricci flow. In particular, we prove that
The dual Bonahon–Schläfli formula
Given a differentiable deformation of geometrically finite hyperbolic $3$-manifolds $(M_t)_t$, the Bonahon-Schlafli formula expresses the derivative of the volume of the convex cores $(C M_t)_t$ in
Infinitesimal rigidity of convex surfaces through the second derivative of the Hilbert-Einstein functional I: Polyhedral case
The paper is centered around a new proof of the infinitesimal rigidity of convex polyhedra. The proof is based on studying derivatives of the discrete Hilbert-Einstein functional on the space of
Continuity of the renormalized volume under geometric limits
We extend the concept of renormalized volume for geometrically finite hyperbolic $3$-manifolds, and show that is continuous for geometrically convergent sequences of hyperbolic structures over an
Hyperbolic Minimal Surfaces and Anti-de Sitter maximal surfaces
We prove that the supremum of principal curvatures of a minimal embedded disc in hyperbolic three-space spanning a quasicircle in the boundary at infinity is estimated in a sublinear way by the norm


Holography and Riemann surfaces
We study holography for asymptotically AdS spaces with an arbitrary genus compact Riemann surface as the conformal boundary. Such spaces can be constructed from the Euclidean AdS_3 by discrete
Hypersurfaces in Hn and the space of its horospheres
Abstract. A classical theorem, mainly due to Aleksandrov [Al2] and Pogorelov [P], states that any Riemannian metric on S2 with curvature K > —1 is induced on a unique convex surface in H3. A similar
Minimal surfaces and particles in 3-manifolds
We consider 3-dimensional anti-de Sitter manifolds with conical singularities along time-like lines, which is what in the physics literature is known as manifolds with particles. We show that the
Variations of the boundary geometry of $3$-dimensional hyperbolic convex cores
A fundamental object in a hyperbolic 3-manifold M is its convex core C(M), defined as the smallest closed non-empty convex subset of M. We investigate the way the geometry of the boundary S of C(M)
L^2 curvature and volume renormalization of AHE metrics on 4-manifolds
This paper relates the boundary term in the Chern-Gauss-Bonnet formula on 4-manifolds M with the renormalized volume V, as defined in the AdS/CFT correspondence, for asymptotically hyperbolic
Quasi-Fuchsian manifolds with particles
We consider 3-dimensional hyperbolic cone-manifolds which are “convex cocompact” in a natural sense, with cone singularities along infinite lines. Such singularities are sometimes used by physicists
On holomorphic factorization in asymptotically AdS 3D gravity
This paper studies aspects of 'holography' for Euclidean signature pure gravity on asymptotically AdS 3-manifolds. This theory can be described as SL(2, ) CS theory. However, not all configurations
The Schwarzian derivative, conformal connections, and Möbius structures
To the memory of Lars V. Ahlfors Despite its well-established role in complex analysis, the Schwarzian derivative remains somewhat mysterious. It is not a derivative, exactly, but what is it? The
The Schläfli formula in Einstein manifolds with boundary
We give a smooth analogue of the classical Schlafli formula, relating the variation of the volume bounded by a hypersurface moving in a general Einstein manifold and the integral of the variation of
Anti-de Sitter space and holography
Recently, it has been proposed by Maldacena that large $N$ limits of certain conformal field theories in $d$ dimensions can be described in terms of supergravity (and string theory) on the product of
