Rings with a Derivation Whose Some Power Image is Contained in the Nuclei or Commutative Center Dedicated to My Retired Colonel Uncle Yu-Chun Cheng on His 80(superscript th) Birthday

環有一導算它的某些冪被包含在核心或交換中心 獻給我退休空軍上校叔叔成嶽群80歲生日

摘要


此篇論文它被證明若R是一非結合質環有一導算d使得d(上標 n)(R)⊆核心且d(上標 3n-2)(R)+d(上標 3n-2)(R)R=d(上標 3n-2)(R)+Rd(上標 3n-2)(R),此處n是一固定正整數,則R是結合的或d(上標 3n-1)=(3n-1)d(上標 3n-2)=0。此部分雄廣[3]中之主要結果。對於非結合單純環情形,一些弱條件也被考慮。

並列摘要


It is shown in this article that if R is a prime nonassociative ring with a derivation d such that d(superscript n)(R) is contained in the nucleus and d(superscript 3n-2)(R)+d(superscript 3n-2)(R)R=d(superscript 3n-2)(R)+Rd(superscript 3n-2)(R) where n is a fixed positive integer then R is associative or d(superscript 3n-1)=(3n-1)d(superscript 3n-2)=0. This partially generalizes the main result in [3]. Some weaker conditions for the simple nonassociative rings are also considered.
