On the Extensions of Zassenhaus Lemma and Goursat’s Lemma to Algebraic Structures

The Jordan–Hölder theorem is proved by using Zassenhaus lemma which is a generalization of the Second Isomorphism Theorem for groups. Goursat’s lemma is a generalization of Zassenhaus lemma, it is an algebraic theorem for characterizing subgroups of the direct product of two groups G1×G2, and it inv...
