The Dixmier-Douady class of groupoid crossed products
Journal of the Australian Mathematical Society
We give a formula for the Dixmier-Douady class of a continuous-trace groupoid crossed product that arises from an action of a locally trivial, proper, principal groupoid on a bundle of elementary C* -algebras that satisfies Fell's condition. 2000 Mathematics subject classification: primary 46L05, 46L55.doi:10.1017/s1446788700008910 fatcat:p3g4eohvwrgvbd2kqvx2ln2toq
