In [8], Scopes verified the Donovan conjecture for blocks of the finite symmetric groups. Her main theorem ( 1.3 below) was proved by finding a sufficient condition for Morita equivalence between two blocks of the same weight. Since there is a close connection between representations of the symmetri
Given a C\*-dynamical system (A, G, :), we discuss conditions under which subalgebras of the multiplier algebra M(A) consisting of fixed points for : are 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 a
