Let L(M) be a class of all groups G in which the normal closure of any element belongs to M; qM is a quasivariety generated by a class M. We consider a quasivariety qH2 generated by a relatively free group in a class of nilpotent groups of class at most 2 with commutator subgroup of exponent 2. It is proved that the Levi class L(qH2) generated by the quasivariety qH2 is contained in the variety of nilpotent groups of class at most 3.

由幂零群的拟变异产生的列维类

令 L(M) 是所有群 G 的一个类,其中任何元素的正态闭包都属于 M;qM 是类 M 产生的拟变异。我们考虑由一类最多为 2 的幂零群中的相对自由群产生的拟变异 qH2,其中交换子子群的指数为 2。证明了 Levi 类 L(qH2)由拟变异 qH2 生成的 最多包含在类别为 3 的幂零群的多样性中。
