Description: |
When, in a semi-abelian category, a truncated simplicial object is considered as a higher extension, the commutators involved in the centrality condition for this extension may be expressed in terms of degenerate simplices. The aim of my talk is to explain some of the simplicial-geometrical ideas behind this result.
Joint work-in-progress with Nelson Martins-Ferreira and George Peschke.
