Definition talk:Short Exact Sequence of Modules

Reverted to the original version, as it is more educational
Not educational. This isn't an understandable exposition. When a short exact sequence is considered, then there is no associated long exact sequence. --Usagiop (talk) 01:40, 5 November 2022 (UTC)


 * sequence $(1)$ is quite confusing. We are not talking about a sequence but an exact sequence. The latter must be linked at least. --Usagiop (talk) 01:48, 5 November 2022 (UTC)


 * The exact sequence was in fact linked but the exposition is weird. I am also tired. --Usagiop (talk) 01:55, 5 November 2022 (UTC)

The definitions and formulations here are indeed sketchy. To avoid idiosyncrasy, let us follow the standard route and work from a source (or even better, multiple). &mdash; Lord_Farin (talk) 10:24, 5 November 2022 (UTC)
