论文摘要
事实证明，中央必不可少的环（其有限等级的添加剂组为有限级的扭转组）是准不变的，但不一定是不变的。无扭转的无扭转有限排名与中央基本的内态戒指是忠实的。该论文将出现在beiträgezur代数和几何 /对代数和几何形状的贡献中。
It is proved that centrally essential rings, whose additive groups of finite rank are torsion-free groups of finite rank, are quasi-invariant but not necessarily invariant. Torsion-free Abelian groups of finite rank with centrally essential endomorphism rings are faithful. The paper will appear in Beiträge zur Algebra und Geometrie / Contributions to Algebra and Geometry.
