This amounts to studying mappings that are given by rational functions rather than polynomials; the map may fail to be defined … See more Rational maps A rational map from one variety (understood to be irreducible) $${\displaystyle X}$$ to another variety $${\displaystyle Y}$$, written as a dashed arrow X ⇢Y, is … See more Every algebraic variety is birational to a projective variety (Chow's lemma). So, for the purposes of birational classification, it is enough to work only with projective varieties, and this is usually the most convenient setting. Much deeper is See more A projective variety X is called minimal if the canonical bundle KX is nef. For X of dimension 2, it is enough to consider smooth varieties in this definition.
