摘要：

We compare the categorical notion of central extension introduced in an earlier paper of ours, which generalized that used previously in non-abelian homological algebra by Fröhlich and Lue, with the notion of centrality arising from commutator theory in universal algebra, showing that they agree in the most important cases.
