定理(Theorem)、引理(Lemma)、推论(Corollary)的定义及LaTeX用法

1、定理(Theorem)

1.1 定义:

Theorem(定理)----a mathematical statement that is proved using rigorous mathematical reasoning. In a mathematical paper, the term theorem is often reserved for the most important results.

主观认识:一个具有 结论性 的、用 数学陈述 的结果,它需要 严格的数学证明

//LaTeX 头部添加
\newtheorem{theorem}{Theorem}[section]

\begin{theorem}
***//定理内容
\label{thm-1}
\end{theorem}

证明:

\begin{proof}
***//证明过程
\end{proof}

2、引理(Lemma)

Lemma(引理)----a minor result whose sole purpose is to help in proving a theorem. It is a stepping stone on the path to proving a theorem. Very occasionally lemmas can take on a life of their own (Zorn’s lemma, Urysohn’s lemma, Burnside’s lemma,Sperner’s lemma).

主观认识:引理是为了 证明定理 而存在的一个 中间步骤

//LaTeX 头部添加
\newtheorem{lemma}{Lemma}[section]

\begin{lemma} 
***//引理内容
\label{lem-1}
\end{lemma}

3、推论(Corollary)

Corollary(推论)-----a result in which the (usually short) proof relies heavily on a given theorem (we often say that \this is a corollary of Theorem A").

主观认识:推论是由 定理 经过 简短推导 而来的结果。

//LaTeX 头部添加
\newtheorem{corollary}{Corollary}[section]

\begin{corollary} 
***//推论内容
\label{cor-1}
\end{corollary}

4、结论:三者的区别

主观结论

推论(Corollary)是由定理(Theorem)推导出来的,定理(Theorem)是由引理(Lemma)推导出来的。总之:引理(Lemma) => 定理(Theorem)=> 推论(Corollary)
