WebThe Jordan-Hölder theorem for groups guarantees that any composition series of a module over a ring are equivalent, so that the lengths of its longest such chains are the same. This makes length a well-defined invariant which is finite iff the module is …

This question hasn't been solved yet WebPublished 2014. Mathematics. Arch. Formal Proofs. This submission contains theories that lead to a formalization of the proof of the Jordan-Hölder theorem about composition series of finite groups. The theories formalize the notions of isomorphism classes of groups, simple groups, normal series, composition series, maximal normal subgroups.

If G has no normal subgroup that is different from G and from the trivial group, then G is a simple group. Otherwise, the question naturally arises as to whether G can be reduced to simple "pieces", and if so, are there any unique features of the way this can be done? talking typing software free downloadWebTheorem 3.
