Let R, m be a local ring commutative and Noetherian . If R is complete or, . more generally, Henselian , one has the KrullαSchmidt uniqueness theorem for direct sums of indecomposable finitely generated R-modules. By passing to the m-adic completion R, we can get a measure of how badly the KrullαSch

Let R be a local ring order, i.e. a one-dimensional local (noetherian) ring whose completion R is reduced, and let M be a finitely generated R-module. We consider two monoids: +(M), which consists of the isomorphism classes of R-modules which arise as direct summands of direct sums of finitely many
Commutative monoids yield an analogy between the theory of factorization in commutative integral domains and the theory of direct sum decompositions of modules. We show that the monoid V (C) of isomorphism classes of a class C of modules with semilocal endomorphism rings is a Krull monoid (Theorem 3
