Méthode des orbites et formules du caractère pour les représentations tempérées d'un groupe algébrique réel réductif non connexeJean-Yves DuclouxJean-Yves DuclouxUniversité Paris 7 UFR de Mathématiques, UMR 7586 2 place Jussieu, F-75251 Paris Cedex 05, France ducloux@math.jussieu.fr Abstract: Let $G$ be a non-connected reductive real Lie group. In this paper, I parametrize the set of irreductible tempered characters of $G$. Afterwards, I describe these characters by means of some ``Kirillov's formulas'', using the descent method near each elliptic element in $G$. If $G$ is linear and connected, the parameters that I use are ``final basic'' parameters in the sense of Knapp and Zuckerman Full text of the article:
