On a category of chains of modules whose endomorphism rings have at most 2n maximal ideals
Abstract
We describe the endomorphism rings in an additive category whose objects are right R-modules M with a fixed chain of submodules 0=M(0)≤ M(1)≤ M(2) ≤ … ≤ M(n)=M and the behaviour of these objects as far as their direct sums are concerned.
