Units of the string link monoids
We show that the map obtained by viewing a geometric (i.e. representative) braid as a string link induces an isomorphism of the n-strand braid group onto the group of units of the n-strand string link monoid.

We prove vanishing results for the unramified stable cohomology of alternating groups.
