摘要: 设σ是一个环R上的自同构, δ是R的一个σ-导子. 通过引进(σ,δ)-SILS弱Armendariz环的概念, 研究一般斜逆Laurent级数环的弱Armendariz性质. 用逐项分析方法证明了当R满足弱-(σ,δ)-相容性且nil(R)是幂零理想时, R是(σ,δ)-SILS弱Armendariz环.

关键词: 斜逆Laurent级数环, 弱Armendariz性质, 弱(σ,δ)相容性

Abstract: By introducing the concept of (σ,δ)-SILS weak Armendariz rings, we investigated the weak Armendariz properties of general skew inverse Laurent series rings. By using the itemized analysis method on series, we prove that if R is weak -(σ,δ)-compatible and nil(R) is a nilpotent ideal, then R is (σ,δ)-SILS weak Armendariz ring.

Key words: skew inverse Laurent series ring, weak Armendariz property, weak(σ,δ)compatible
