This attribute controls the content of the description and og:description elements. | In mathematics, and especially in homotopy theory, a crossed module consists of groups $ G $ and $ H $, where $ G $ acts on $ H $ by automorphisms (which we will write on the left, $ (g,h)\mapsto g\cdot h $ , and a homomorphism of groups
$ d\colon H\longrightarrow G, $
that is equivariant with respect... |
