birational geometry
[baɪˈreɪʃənəl dʒiˈɒmətri]
noun
geometria biracional
1. A branch of algebraic geometry that studies properties of algebraic varieties that are invariant under birational maps, which are rational maps with rational inverses
Birational geometry allows mathematicians to classify algebraic varieties by identifying those that are equivalent under birational transformations.
A geometria biracional permite que matemáticos classifiquem variedades algébricas identificando aquelas que são equivalentes sob transformações biracionais.
2. The study of geometric structures that remain unchanged under birational equivalence, focusing on properties like dimension and singularities
In birational geometry, two varieties are considered equivalent if there exists a birational map between them.
Em geometria biracional, duas variedades são consideradas equivalentes se existe um mapa biracional entre elas.
This is a specialized technical term used primarily in academic mathematics. It appears in university-level algebraic geometry courses and research publications in both Brazil and Portugal. The term maintains the same meaning and usage across all Portuguese-speaking regions, with no significant regional variations. It is part of the standard mathematical lexicon taught in graduate programs at major institutions like USP (Universidade de São Paulo) and IMPA (Instituto Nacional de Matemática Pura e Aplicada) in Brazil.
