Abstract
A non-zero constant Jacobian polynomial map $F=(P,Q):\mathbb{C}^2 \rightarrow \mathbb{C}^2$ has a polynomial inverse if the component $P$ is a simple polynomial, i.e. its regular extension to a morphism $p:X\rightarrow \mathbb{P}^1$ in a compactification $X$ of $\mathbb{C}^2$ has the following property: the restriction of $p$ to each irreducible component $C$ of the compactification divisor $D = X-\mathbb{C}^2$ is of degree $0$ or $1$.
