{wiki=Mori–Nagata_theorem}
The Mori–Nagata theorem is a result in algebraic geometry, particularly concerning the structure of algebraic varieties and their properties under certain conditions. Named after Shigeo Mori and Masayuki Nagata, the theorem deals with the existence of a specific type of morphism called a "rational map" between varieties.
