lemma
의미: A subsidiary or intermediate result proved in order to assist in the proof of a larger theorem. In linguistics, the canonical or dictionary form of a word.
In mathematics, a lemma is a stepping stone — a result that is not significant in its own right but is essential for establishing a more important theorem. Famous examples include Zorn's lemma and the pumping lemma. Ironically, some lemmas (notably Zorn's) have become more celebrated than the theorems they were designed to support. In computational linguistics, lemmatisation is the process of reducing a word to its base form — 'running' becomes 'run,' 'better' becomes 'good.' The plural can be either 'lemmas' or the Greek 'lemmata.'
예문
- The proof of the main theorem relies on a technical lemma establishing that the sequence converges uniformly. 主定理的证明依赖于一个技术性引理,该引理确立了数列一致收敛。La demostración del teorema principal se basa en un lema técnico que establece que la sucesión converge uniformemente.主定理の証明は、数列が一様に収束することを示す技術的な補題に依拠している。주정리의 증명은 수열이 균등하게 수렴함을 확립하는 기술적 보조정리에 의존하고 있다.
- Zorn's lemma, though originally a tool for proving other results, has become one of the most widely cited propositions in set theory. 佐恩引理虽然最初只是证明其他结果的工具,但已成为集合论中被引用最广泛的命题之一。El lema de Zorn, aunque originalmente concebido como herramienta para demostrar otros resultados, se ha convertido en una de las proposiciones más citadas de la teoría de conjuntos.ツォルンの補題は、元々は他の結果を証明するための道具であったが、集合論において最も広く引用される命題の一つとなった。초른의 보조정리는 원래 다른 결과를 증명하기 위한 도구였으나, 집합론에서 가장 널리 인용되는 명제 중 하나가 되었다.
- The search engine uses lemmatisation to match queries with documents, ensuring that 'organising' and 'organised' return the same results. 该搜索引擎使用词形还原将查询与文档匹配,确保'organising'和'organised'返回相同的结果。El motor de búsqueda utiliza la lematización para emparejar consultas con documentos, garantizando que «organising» y «organised» devuelvan los mismos resultados.その検索エンジンはレンマ化を用いてクエリと文書をマッチングし、「organising」と「organised」が同じ結果を返すようにしている。그 검색 엔진은 표제어 추출(lemmatisation)을 사용하여 쿼리와 문서를 매칭하며, 'organising'과 'organised'가 같은 결과를 반환하도록 한다.
