DESCRIPTION:Piotr Przytycki (McGill University)\nThis is joint work with S
 tephane Lamy. Let k be a field of characteristic zero. The tame automorphi
 sm group Tame(k^3) is generated by the affine automorphisms of k^3\, and t
 he automorphisms of the form (x\,y\,z)->(x\,y\,z+P(x\,y))\, where P is a p
 olynomial in k[x\,y]. We prove that every subgroup of Tame(k^3) is virtual
 ly solvable or contains a non-abelian free group.
