Description
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.
