- W4287646039 abstract "For any $n$, we describe all endomorphisms of the braid group $B_n$ and of its commutator subgroup $B'_n$, as well as all homomorphisms $B'_nto B_n$. These results are new only for small $n$ because endomorphisms of $B_n$ are already described by Castel for $nge 6$, and homomorphisms $B'_nto B_n$ and endomorphisms of $B'_n$ are already described by Kordek and Margalit for $nge 7$. We use very different approaches for $n=4$ and for $nge 5$." @default.
