AbstarctLet γ n = [x 1 ,…,x n ] be the n th lower central word. Denote by X n the set of γ n -values in a group G and suppose that there is a number m such that $|{g^{{X_n}}}| \le m$ for each g ∈ G . We prove that γ n+ 1 (G ) has finite (m, n ) -bounded order. This generalizes the much-celebrated theorem of B. H. Neumann that says that the commutator subgroup of a BFC-group is finite.

关于有限幂群
摘要γ n = [X 1 ,…,X n ] 成为n 较低的中心词。表示为X n 的集合γ n - 组中的值G 并假设有一个数字米 这样$|{g^{{X_n}}}| \le m$ 对于每个G ∈G . 我们证明γ n+ 1 (G )有有限(米,n ) - 有界顺序。这推广了广为人知的 BH Neumann 定理,即 BFC 群的交换子群是有限的。
