WebThe Brauer group is functorial in the following sense. Given an extension K=k, extension of scalars gives a homomorphism Br(k) !Br(K), [A] 7![A kK]. We de ne the relative Brauer group, Br(K=k), to be the kernel of this homomorphism, consisting of the (equivalence classes) of nite central simple k-algebras split by K(A K˘=M n(K) for some n). Web2 Artin’s Theorem Let R(G) be the subgroup of A(G) consisting of all integer linear combinations of characters of representations of G. If V and Ware representations of Gthen V⊗ C W under the action g(v⊗ w) = gv⊗ gwis another representation, and its character is the product of the characters of V and W. Hence, R(G) is a commutative ring ...
