Abstract
The proof of the Tits alternative for is completed. The main tool is a Kolchin type theorem, proved in this paper. It states that a finitely generated subgroup of consisting of unipotent automorphisms can be conjugated into an upper-triangular subgroup (this is interpreted via train-tracks).
