Images of Locally Finite Derivations of Polynomial Algebras in Two Variables
arXiv:1004.0521
Abstract
In this paper we show that the image of any locally finite -derivation of the polynomial algebra in two variables over a field of characteristic zero is a Mathieu subspace. We also show that the two-dimensional Jacobian conjecture is equivalent to the statement that the image of every -derivation of such that and is a Mathieu subspace of .
