Relative differential K-characters

We define a group of relative differential K-characters associated with a smooth map between two smooth compact manifolds. We show that this group fits into a short exact sequence as in the non-relative case. Some secondary geometric invariants are expressed in this theory.

Unitaire multiplicatif K-moyennable

Nous generalisons la theorie de la K-moyennabilite au cas d'un unitaire multiplicatif regulier V. Nous montrons que si (H,V,U) est un systeme de Kac K-moyennable, alors pour toute S-algebre A, les algebres $ A\times_{m}\hat S$ (produit croise maximal) et $ A\times \hat S$ (produit croise reduit) sont KK-equivalentes ou S est la $C^*$-algebre de Hopf reduite associee a V.
