设k为有理数域Q上的有限次代数数域。我们用0表示k中的整数环。一般来说,对于一个包含1的泛域Ω的子域a,我们用GL(n, a)表示GL(n, Ω)的子群,它由矩阵x = (xij)组成,其中xij∈a, det x∈a x是a的单位群。现在,我们考虑在k上定义的GL(n, Ω)中的代数群G。
Let k be an algebraic number field of finite degree over the field Q of rational numbers. We denote by o the ring of integers in k. In general, for a subring A, containing 1, of a universal domain Ω we denote by GL(n, A) the subgroup of GL(n, Ω) consisting of matrices x = (xij ) with xij ∈ A and det x ∈ A ×, the group of units of A. Now, we consider an algebraic group G in GL(n, Ω) defined over k.
