dc.descriptionWe present sufficient conditions for HNN extensions to be inner amenable, respectively ICC, which give necessary and sufficient criteria among Baumslag-Solitar groups. We deduce that such a group, viewed as acting on its Bass-Serre tree, contains non trivial elements which fix unbounded subtrees.
dc.description16 pages, in french. Slightly stronger results and typographic corrections. To appear in Ann. Inst. Fourier (Grenoble)
