The bracket width for Lie algebras of vector fields is finite

Rafael B. Andrist, Andriy Regeta

We prove that the bracket width of the Lie algebra of vector fields on any smooth affine algebraic variety of dimension $n$ is at most $(n + 1)^{2}$ . We give improved bounds for some f…

Infinite transitivity and polynomial vector fields

Rafael B. Andrist, Ivan Arzhantsev

We prove that for many pairs $H_{1}, H_{2}$ of root subgroups of the automorphism group $Aut (C^{2})$ the diagonal action of the group generated by $H_{1}, H_{2}$ on $(\mathbb…

Varieties Characterized by their Endomorphisms

Rafael Andrist, Hanspeter Kraft

We show that two varieties X and Y with isomorphic endomorphism semigroups are isomorphic up to field automorphism if one of them is affine and contains a copy of the affine line.…
