Soit M une variété différentiable de dimension n qui admet un difféomorphisme de type quasi-Anosov. Si n=3 alors on a l'altenative suivante, ou bien , et dans ce cas le difféomorphisme est en fait d'Anosov, ou bien le goupe fondamental de M contient une copie de . Si n=4, alors Π1(M) contient une copie de , pourvu que le difféomorphisme ne soit pas d'Anosov.
Let M be an n-dimensional manifold supporting a quasi-Anosov diffeomorphism. If n=3 then either , in which case the diffeomorphisms is Anosov, or else its fundamental group contains a copy of . If n=4 then Π1(M) contains a copy of , provided that the diffeomorphism is not Anosov.
