"A Galois correspondence for crossed products"

We consider a discrete group G acting by outer automorphisms on a simple unital C*-algebra A. We address the problem of characterising the C*-algebras lying between A and its crossed product by G. The main result is that these are parameterised by the subgroups of G. This is joint work with Jan Cameron.
