摘要: 在Monoid分次环范畴中, 利用M分次环e分量中的幂 等元性质, 证明三类M分次环具有Block分解, 并且这种分解本质上是惟一的.

关键词: Monoid分次环, 齐次幂等元, 分次Block

Abstract: In the category of Monoid-graded rings, by means of the idempotent pro perties in e- component of M-graded rings, we show that three kinds of M-graded rings admit a graded ring decomposition into finite indecomposable graded rings and that this indecomposable decomposition is unique in a strong sense.

Key words: Monoid-graded ring, homogeneous idempotent, graded Block
