Selfdual spaces with complex structures, Einstein-Weyl geometry and geodesics

David M J. Calderbank, Henrik Pedersen (2000)

Annales de l'institut Fourier

We study the Jones and Tod correspondence between selfdual conformal $4$ -manifolds with a conformal vector field and abelian monopoles on Einstein-Weyl $3$ -manifolds, and prove that invariant complex structures correspond to shear-free geodesic congruences. Such congruences exist in abundance and so provide a tool for constructing interesting selfdual geometries with symmetry, unifying the theories of scalar-flat Kähler metrics and hypercomplex structures with symmetry. We also show that in the presence...

Straightening cell decompositions of cusped hyperbolic 3-manifolds

Marina Pescini (1998)

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti Lincei. Matematica e Applicazioni

Let $M$ be an oriented cusped hyperbolic 3-manifold and let $τ$ be a topological ideal triangulation of $M$ . We give a characterization for $τ$ to be isotopic to an ideal geodesic triangulation; moreover we give a characterization for $τ$ to flatten into a partially flat triangulation. Finally we prove that straightening combinatorially equivalent topological ideal cell decompositions gives the same geodesic decomposition, up to isometry.

Structures affines et projectives sur les surfaces complexes

Bruno Klingler (1998)

Annales de l'institut Fourier

Une structure complexe affine (resp. projective) sur une surface complexe est la donnée d’un atlas de cartes à valeur dans $ℂ^{2}$ (resp. $P^{2} ℂ$ ) à changements de cartes localement constants dans le groupe affine $A (2, ℂ)$ (resp. le groupe $P G L (3, ℂ)$ ). Dans cet article nous classifions les surfaces complexes affines et calculons, à surface complexe $S$ fixée, l’espace de déformation des structures complexes affines sur $S$ compatibles avec sa structure analytique. Nous montrons aussi que toute structure projective sur une surface...

Surface Projective Convexe de volume fini

Ludovic Marquis (2012)

Annales de l’institut Fourier

Une surface projective convexe est le quotient d’un ouvert proprement convexe $Ω$ de l’espace projectif réel $ℙ^{2} (ℝ)$ par un sous-groupe discret $Γ$ de ${SL}_{3} (ℝ)$ . Nous donnons plusieurs caractérisations du fait qu’une surface projective convexe est de volume fini pour la mesure de Busemann. On en déduit que si $Ω$ n’est pas un triangle alors $Ω$ est strictement convexe, à bord $𝒞^{1}$ et qu’une surface projective convexe $S$ est de volume fini si et seulement si la surface duale est de volume fini.
