摘要
构造了l-群类Bw0 ,证明Bw0 是一个扭类 ,并刻划了其扭根Bw0 (G) ,得到Bw0 (G) =∩u这一重要结果。同时 ,还详细探讨了Bw0 中的格序群的特点 ,获得了如下主要结论 :( 1)G∈Bw0 ,则G有基 ∩α∈EVα=( 0 ) ,其中 {Vα|α∈E}是G的本质值全体。( 2 )G∈Bw0 , 0 <g∈G ,若 g有一个特殊值 ,则 g必超过一个基元素。最后建立了该扭类与其他已知l-群类的关系 ,得到Bw0 ∩Fv2
This article constructs on variety of l-groups B w 0,and prove it is a torsion class.We destribe its torsion radical B w 0(G),and attain B w 0(G)=∩u.At the same time,we discuss the properties of l-groups which belong to B w 0 and receive such important results as: \ \ (1) If G∈ B w 0,then G has bases if and onty if ∩α∈EV α=(0). (2) G∈B w 0,0<g∈G,if g has a special value,then g must beyond one of basic elements. \ \ Constructs the relationships between Bw 0 and other l-gronp,varieties and attain Bw 0∩Fv 2Fw 0
