Résumé

On établit des résultats de l'analyse harmonique locale nécessaires pour la formule des traces invariante d'Arthur pour les revêtements de groupes réductifs connexes. Plus précisément, on démontre pour les revêtements locaux (1) la formule de Plancherel et des préparatifs reliés, (2) la normalisation des opérateurs d'entrelacement soumise aux conditions d'Arthur, (3) le comportement local de caractères de représentations admissibles dans le cas non archimédien, et (4) la partie spécifique de la formule des traces locale invariante. Comme un sous-produit de la démonstration de la formule des traces locale invariante, on obtient aussi la densité de caractères tempérés pour les revêtements.

Abstract

We establish some results in local harmonic analysis which are necessary for Arthur's invariant trace formula for coverings of connected reductive groups. More precisely, for local coverings we will study (1) the Plancherel formula and its preparations, (2) the normalization of intertwining operators subject to Arthur's conditions, (3) the local behavior of characters of admissible representations in the nonarchimedean case, and (4) the genuine part of the invariant local trace formula. As a byproduct of the invariant local trace formula, we deduce the density of tempered characters for coverings.
