Abstract/Résumé:
An elementary groupoid construction is shown to underlie Rieffel’s Hilbert module construction of a non-trivial projection in the irrational rotation C*-algebra.
Une construction élémentaire de groupoïde se révèle à la base de la construction de Rieffel à module de Hilbert d’un projecteur non-trivial dans la C*-algèbre d’une rotation irrationnelle.
Keywords: Irrational rotation algebra, Rieffel projection, groupoid construction
