Abstract
A polynomial in n variables is called a coordinate polynomial if it is a component of a polynomial automorphism of n-space. For n=2 and a ground field of characteristic zero, we show that a polynomial is a coordinate polynomial if its composition with a dominant endomorphism of 2-space is a coordinate polynomial.
