[KK-théorie des systèmes semi-circulaires A-valués]
Comptes Rendus. Mathématique, Tome 354 (2016) no. 1, pp. 87-90.

On calcule dans cet article la KK-théorie de systèmes semi-circulaires A-valués à l'aide d'outils développés par Pimsner (voir [1]) pour étudier les algèbres de Toeplitz généralisées.

We compute in this article the KK-theory of A-valued semi-circular systems thanks to tools developed by Pimsner (see [1]) to study generalized Toeplitz algebras.
