On the Bockstein lemma
The Bockstein Lemma is used in calculating homotopy groups and to determine the differentials of the Bockstein spectral sequence. The homology version of the Bockstein Lemma is proved in the paper under review, correcting a sign error from a previous work. Two other results, which are variations of the Bockstein Lemma, are proved and some examples related to them are also given.
