Splitting of Short Exact Sequences for Groups


(1.2) G1 α1 −−−→ G2 α2 −−−→ · · · αn−1 −−−−→ Gn, and it must be exact at each Gi for 1 < i < n. Exact sequences can also be of infinite length in one or both directions. We will only deal with short exact sequences here. Exact sequences first arose in algebraic topology, and the later development of homological algebra (the type of algebra underlying… (More)
