摘要:

考虑四阶矩阵环M4(R)的子环S4(R)的半交换性和Armendariz性质, 证明了如果R是reduced环, α1234是R的相容自同态, 则S4(R)是半交换Armendariz环.

关键词: Armendariz环, 半交换环, reduced环, 相容自同态

Abstract:

We discussed the semicommutative and Armendariz properties of the subring S4(R) of 4×4 matrix ring M4(R). It was shown that S4(R) is an Armendariz and semicommutative ring if R is a reduced ring with compatible endomorphisms α1234.

Key words: Armendariz ring, semicommutative ring, reduced ring, compatible endomorphism
