Abstract: | Let G be an infinite group and m
{2k | k
N*}. In this paper, we prove that G satisfies the law xm, ym] = 1 if and only if in any two infinite subsets X and Y of G, there exist a
X and b
Y such that am,bm] = 1. We also prove that G satisfies the law (x1mx2m
xnm)2 = 1 if and only if in any n infinite subsets X1, X2,..., Xn, there exist ai
Xi (i = 1,..., n) such that (a1ma2m
anm)2 = 1.2000 Mathematics Subject Classification: 20F99 |
