   Format: MarkdownItexTo add the old entry [[birational geometry]] I added a number of classical, very geometric, [[algebraic geometry]] entries [[rational map]], [[birational map]], [[rational variety]], [[image of a rational map]], [[unirational variety]] and a number of redirects. The notion of an image is a bit unusual because the varieties and rational maps do not make a category, as the composition is not always defined. However the notion of the image is still very natural here. For the concept of dominant rational map I did not make a separate entry but discussed it within [[rational map]] and made redirects.
