The set of division algebras central and finite dimensional over a field F ลฝ . are nicely parameterized by the Brauer group Br F , which is naturally 2 ลฝ โ ท . isomorphic to the Galois cohomology group H G , F . Since the latter F sep is an arithmetic invariant, the theory of F's division algebras and
Suppose that (G, T ) is a second countable locally compact transformation group given by a homomorphism l: G ร Homeo(T ), and that A is a separable continuous-trace C\*-algebra with spectrum T. An action :: G ร Aut(A) is said to cover l if the induced action of G on T coincides with the original one
