In mathematics and specifically in algebraic geometry, the dimension of an algebraic variety may be defined in various equivalent ways. Some of these definitions are of geometric nature, while some other are purely algebraic and rely on commutative algebra. Some are restricted to algebraic varieties while others apply also to any algebraic set. Some are intrinsic, as independent of any embedding of the variety into an affine or projective space, while other are related to such an embedding.

  • Em matemática, a dimensão de uma variedade algébrica V em geometria algébrica é definida, informalmente falando, como o número de funções racionais independentes que existem em V. Por exemplo, uma curva algébrica tem por definição dimensão 1. Isto significa que dadas quaisquer duas funções racionais F e G, sobre elas deve-se satisfazer alguma relação polinomial Isto implica que F e G estão delimitadas a terem valores relacionados (até alguma finita liberdade de escolha): eles não podem ser verdadeiramente independentes.
