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

Key words: direct sums decompositions, isomorphically complement (maximal) direct summands, homologically independent
