Suppose that (G, T ) is a second countable locally compact transformation group given by a homomorphism l: G Γ„ Homeo(T ), and that A is a separable continuous-trace C\*-algebra with spectrum T. An action :: G Γ„ Aut(A) is said to cover l if the induced action of G on T coincides with the original one
