We present a new method of establishing a bijective correspondence - in fact, a lattice isomorphism - between invariant ideals of C*-algebras and their crossed products by a fixed locally compact group. It was already known that such a correspondence exists whenever the group is amenable, but our results hold for any locally compact group under a natural form of coaction invariance. Time permitting, we also introduce a similar result for ideals of Fell bundles over groupoids. Joint work with Matthew Gillespie, S. Kaliszewski, and Dana P. Williams.
