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. WebJun 22, 2024 · We’re going to start out by proving Zassenhaus’ Lemma. At least that will be our first significant result for this entry. Before we can do that, though, we’ll have to establish several smaller lemmas to support the proof. The first of these is mostly a useful observation. Finally, we’ll end the entry with a proof of the Jordan Holder ...
