In this paper, we introduce the concepts of semisimple,totally semisimple S-sys-tems and M-projective S-system ,etc.

引进了半单、全半单Ｓ—系及Ｍ—投射Ｓ—系等概念，讨论了它们的一些性质，得到了一些重要的结果；并研究了所有全单Ｓ—系均Ｓ—投射的幺半群，推广了Ｊ。

2)let R be kthe-semisimple rings,for any x,y∈R,there exist integers m=m(x,y)≥n=n(x,y)≥0,fx,y(t)∈t2Z[t],such that fx,y(xmy)-yxn∈Z(R) or fx,y(yxm)-yxn∈Z(R),then R is commutative.

2)设R为k the半单纯环,若对R中任意x,y,存在整数m=m(x,y)≥n=n(x,y)≥0,多项式fx,y(t)∈t2Z[t]使得fx,y(xmy)-yxn∈Z(R)或fx,y(yxm)-yxn∈Z(R),则R为交换环。

The semisimplicity of pointed YD Lie algebras was characterized by means of Killing forms.

利用Killing型来判断点YD-李代数的半单性,得出了如下结论:如果有限维点YD-李代数L的Killing型是非退化的,那么L是半单的,并且L是它本身的所有极小YD-理想的直和;这些极小YD-理想所对应的Killing型两两正交。

By describing general superfluous convex l-subgroups in this paper, we prove the following results: If G is a normal-valued l-group, then (1)T= {x∈G|x<<u, u is a strong unit of G} ; (2) T = 0 iff G is l- isomorphic to a subdirect product of simple l-groups with semisimplicity.

证明了如下结果:如 果G是正规值l-群,则(1)T={x∈G|x<

In this paper we consider the semisimplicity of implicative BCK-alge-bras and obtain several equivalent conditions which an implicative BCK-algebra is semisimple.

本文考虑关联BCK－代数的半单性，得到这类代数为半单的若干等价条件。

In order to calculate efficiently the simplest normal form(SNF)of differential semi-simple systems without center manifold reduction,the relationship between the SNF and the original equations was deducted based on matrix representation method.

为了在不经中心流形降维的情况下高效计算半单系统的最简规范形,基于矩阵表示法研究了半单系统的最简规范形。

2)Let R be kothe-semisimple rings,for any x,y∈R,there exist integers m=m(x,y)>1,n=n(x,y)>1, such that (x~my)~n-yx~m∈Z(R),then R is commutative.

2)设R为kothe半单环,若对R中任意元x,y,存在整数m=m(y)>1,n=n(x,y)>1,使得(xmy)n-yxm∈Z(R)则R为交换环。

Furdermore,we define two kinds of special rings: n-p-semisimple rings and Gp-semisimple rings.

由此构造了两种特殊的环:n-p-半单环与Gp-半单环,并用新引入的模对它们分别进行了刻化。

Furthermore, we define a kind of new rings by means of them ,called N-semisimple rings.

本文引入了N-投射模、N-内射模的概念,由此构造了一种环,称为N-半单环,并且证明出NoetherN-半单环是介于半单环与左遗传环之间的一种环。
