摘  要:  We give a groupoid version of Mackey normal subgroup analysis in a C*-algebraic framework. More precisely, we describe the C*-algebra of a groupoid which is an extension by a group bundle. When the group bundle is abelian, one obtains a twisted groupoid C*-algebra. C*-bundles and the canonical weight of a group bundle play a crucial role in this study. This is joint work with M. Ionescu, A. Kumjian, A. Sims and D. Williams.
