直和分解对直和项的遗传性

Hereditariness of Direct Sum Decomposition to Direct Summand

通过同调无关及连续模的推广,给出遗传性问题有肯定解答的两个充分条件,并讨论了同构补(极大)直和项的直和分解.

In terms of homological independence and a sufficient conditions for the decompositions of isomorphi generalization of continuous modules, we presented two inheritance problem to have an affirmative answer. We also discussed direct sum cally complement （maximal） direct summands.
