WebThese theorems do not provide a universal classification theorem for all abelian categories. The problem with the Jordan-Holder theorem is that not all objects in an¨ abelian category has a maximal chain of subobjects, while the problem for the Krull-Schmidt-Remak theorem is that is requires that the endomorphisms of certain objects Web10 jan. 2024 · and well done. $\blacksquare$ Section 1.3.
