Description: |
The aim of this talk is to explain the concept of double central extension from the point of view of relative commutator theory. We shall focus on one concrete situation: the reflection of loops to groups. First we recall how the Galois theoretic approach to relative commutators arose out of Tomas Everaert's work in the context of Omega-groups. Then we show how the abstract definition applies to the case of loops, where the associator is an example of a relative commutator.
