Abstract
We study the Lie algebra of polynomial vector fields on a smooth Danielewski surface of the form with . We provide explicitly given generators to show that: 1. The Lie algebra of polynomial vector fields is generated by complete vector fields. 2. The Lie algebra of volume-preserving polynomial vector fields is generated by finitely many vector fields, whose number depends on the degree of the defining polynomial. 3. There exists a Lie sub-algebra generated by LNDs whose flows generate a group that acts infinitely transitively on the Danielewski surface. The latter result is also generalized to higher dimensions where .
