Soit B n ' le groupe dérivé du groupe de tresses B n . On montre que Aut(B n ' )=Aut(B n ) pour n≥4, ce qui répond à une question posée par Vladimir Lin.

Let B n ' be the commutator subgroup of the braid group B n . We prove that Aut(B n ' )=Aut(B n ) for n≥4. This answers a question asked by Vladimir Lin.
