To a complex projective structure $\Sigma$ on a surface, Thurston associates a locally convex pleated surface. We derive bounds on the geometry of both in terms of the norms $\|\phi_\Sigma\|_\infty$ and $\|\phi_\Sigma\|_2$ of the quadratic differential $\phi_\Sigma$ of $\Sigma$ given by the Schwarzian derivative of the associated locally univalent map. We show that these give a unifying approach that generalizes a number of important, well known results for convex cocompact hyperbolic…

In this paper, we use the Weil-Petersson gradient flow for renormalized volume to study the space $CC(N;S,X)$ of convex cocompact hyperbolic structures on the relatively acylindrical 3-manifold
Notes on the Schwarzian tensor and measured foliations at infinity of quasifuchsian manifolds.
The boundary at infinity of a quasifuchsian hyperbolic manifold is equiped with a holomorphic quadratic differential. Its horizontal measured foliation $f$ can be interpreted as the natural analog of
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

In this paper we study the injectivity radius based at a fixed point along Weil-Petersson geodesics. We show that the square root of the injectivity radius based at a fixed point is $The dual Bonahon-Schl\"afli formula Given a differentiable deformation of geometrically finite hyperbolic 3-manifolds (Mt)t , the Bonahon-Schläfli formula [Bon98a] expresses the derivative of the volume of the convex cores (CMt)t in 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 The dual volume of quasi-Fuchsian manifolds and the Weil-Petersson distance Making use of the dual Bonahon-Schlafli formula, we prove that the dual volume of the convex core of a quasi-Fuchsian manifold$M$is bounded by an explicit constant, depending only on the topology Measured foliations at infinity of quasi-Fuchsian manifolds near the Fuchsian locus Given a pair of measured foliations (F+,F−) which fill a closed hyperbolic surface S, we prove that for t > 0 sufficiently small, tF+ and tF− can be uniquely realised as the measured foliations at A bound on the$L^2$-norm of a projective structure by the length of the bending lamination • Mathematics • 2022 One can associate to a complex projective structure on a surface holomorphic quadratic differential Φ via the Schwarzian derivative and a bending lamination λ via the Thurston parameterization.
