This result is no longer true in general if is a regular map. However, it still works for a large family of regular maps that we call quasi-polynomial maps.engjournal articlehttp://arxiv.org/pdf/1212.1811v3.pdfhttp://link.springer.com/open access512.7Polynomial and regular maps and imagesQuasi-polynomial mapsSet of points at infinityConnectedness.Geometria algebraica1201.01 Geometría Algebraica
