Combinatorial methods in Teichmüller theoryDisarlo, Valentina 14 June 2013 (has links) (PDF)
In this thesis we deal with combinatorial and geometric properties of arc complexes and triangulation graphs, and we will provide some applications to the study of the mapping class group and to the Teichmüller theory of a bordered surface. The thesis is divided into two parts. In the former we deal with the problem of combinatorial rigidity of arc complexes. In the latter we study some large-scale properties of the arc complex and the 1-skeleton of its dual, the so-called ideal triangulation graph.

Combinatorial methods in Teichmüller theory / Méthodes combinatoires en théorie de TeichmüllerDisarlo, Valentina 14 June 2013 (has links)
Dans cette thèse nous étudions certains propriétés combinatoires et géométriques des complexes d'arcs des surfaces de type fini. Nous démontrons que le groupe d'automorphisme du complexe d'arcs est le mapping class group de la surface. Nous étudions aussi le graphe des triangulations idéales et nous donnons certains applications au espaces de Teichmueller des surfaces avec bord . / In this thesis we deal with combinatorial and geometric properties of the arc complex of a surface of finite type. We prove that its automorphism group is isomorphic to the mapping class of the surface. Furthermore, we investigate the geometric properties of the ideal triangulation graph of a surface and provide some application to Teichmueller theory of a surface with boundary .
