First, we give general results relating the b-completion of a product to the b-completion of its factors, the b-completion of a quotient, and the dependence of the b-completion on the bundle chosen to form it. Second, we relate (when possible) some b-completions to those of Riemannian metrics, and study invariant connections on homogenous spaces. Some particular examples are also considered.engjournal articlehttp://www.sciencedirect.com/science/article/pii/S0362546X01004175http://www.sciencedirect.comrestricted access512.7B-completionHomogeneus reductive spacesSingularityGeometria algebraica1201.01 Geometría Algebraica
