Maximal Coactions

Abstract

A coaction δ of a locally compact group G on a C *-algebra A is maximal if a certain natural map from A × δ G × δ G onto A ⊗ K(L 2 (G)) is an isomorphism. All dual coactions on full crossed products by group actions are maximal; a discrete coaction is maximal if and only if A is the full cross-sectional algebra of the corresponding Fell bundle. For every… (More)
