| Mar 6, 2021 at 7:17 | comment | added | David Roberts♦ | Loday's paper cites an older paper of his on crossed modules of groups, so that thread doesn't go back further. The 1960 paper Analytic group kernels and Lie algebra kernels by Macauley (cited by Mackenzie) almost defines a crossed module, since it takes some of the theory from Eileberg and Mac Lane where they use "abstract kernels", secretly related to crossed modules, and develops it in the case of analytic groups (pretty much just Lie groups, really) | |
