摘 要: | 令G是一个l-群,G的一个凸l-子群A叫做多余的,如果对G的任-凸l-子群W,只要A∨W=G,就有W=G.复令R(G)为G的所有多余凸l-子群的集合并生成的凸l-子群.我们证明了R(G)是l-群G的一种报并且是在Amitsur-Kurosh意义下的根.进一步我们得到了有限值l-群的半单结构定理即R(G)=0当且仅当Gl-同构于具有半单性的单l-群的亚直积,同时我们还得到了一系列有意义的推论.

Abstract: | Let Gbe an l-group,one convex l-subgroup A of G is said to be superfluous, if A∨V W = G for an arbitary convex l-subgroup W of G, then W = G. Again let R(G) be the convex l-subgroup which is generated by the union of all superfluous convex subgroups of G. We prove that R(G) is one kind of radical of l-group G in Amitsur-Kurosh sence. Furthermore, we obtain the semisimple structure theorem for finite-valued l-groups,i.e. R(G) = 0 iff G is l-isomorphic to a subdirect product of simple l-groups with semisimplicity. Moreover, we also obtain some important corollaries. |
