Cette thèse est consacrée à l’étude de la série principale unitaire de certains groupes de Lie semi-simples, du point de vue de la géométrie non-commutative. Pour une famille de sous-groupes paraboliques minimaux de composante de Levi L fixée, nous décrivons la famille des représentations de la série principale unitaire associées au moyen de C*-modules sur C*(L). Cette construction s’inspire de celle des modules d’induction de M. A. Rieffel et nous proposons plusieurs modèles pour les C*-modules obtenus, qui reflètent à ce niveau global les réalisations classiques des représentations de la série principale. En rang réel 1, nous caractérisons certains opérateurs bornés sur ces modules, obtenant ainsi un résultat d’irréductibilité analogue à ...
