摘要 研究了具有w-子模链条件的模上同态,推广了Schur引理,证明了在Krull-Remak-Schmidt定理的观点下,几类w-模可以唯一分解为自同态环是局部环的不可分解子模的直和. In this paper,we investigate the homomorphisms on several classes of w-modules which satisfy ascending and descending chain conditions on w-submodules and generalize the Schur lemma.Moreover,we discuss the uniqueness problem of direct decomposition of modules in view point of the Krull-Remak-Schmidt theorem and prove that several classes of w-modules can be decomposed into a direct sum of directly indecomposable submodules with local endomorphism rings.
