| dc.description | Given a C*-dynamical system (A,G,α), we discuss conditions under which subalgebras of the multiplier algebra M(A) consisting of fixed points for αare Morita-Rieffel equivalent to ideals in the crossed product of A by G. In case G is abelian we also develop a spectral theory, giving a necessary and sufficient condition for αto be equivalent to the dual action on the cross-sectional C*-algebra of a Fell bundle. In our main application we show that a proper action of an abelian group on a locally compact space is equivalent to a dual action. | |
