更改文本中间的假设标签

我有以下文档，其中我在“主要”部分中指定了假设 1,2。

\documentclass[12 pt,a4paper, oneside, openany, notitlepage]{article}
\input epsf
\usepackage{subcaption}
\usepackage{graphicx}
\usepackage[usenames,dvipsnames]{xcolor}
\usepackage{amsmath, amssymb, graphics}
\usepackage{mathtools}
\newcounter{mathematicapage}
\usepackage{amsthm}
\usepackage{amsfonts}
\usepackage[inner=1.25in,outer=1.25in,bottom=1.25in,top=1.25in]{geometry}
\usepackage{setspace}
\onehalfspacing
 \newtheoremstyle{mystyle}% name
  {\topsep}% Space above
  {\topsep}% Space below
  {\normalfont}% Body font
  {}% Indent amount
  { \color{red}}% Theorem head font
  {.}%Punctuation after theorem head
  {.5em}%Space after theorem head
  {}% theorem head spec
\theoremstyle{mystyle}
\newtheorem{assumptionex}{Assumption}
\newenvironment{assumption}
  {\pushQED{\qed}\renewcommand{\qedsymbol}{$\bullet$}\assumptionex}
  {\popQED\endassumptionex}


\begin{document}
\section{Main}
\begin{assumption}
Blah
\end{assumption}

\begin{assumption}
Blah2
\end{assumption}

\section{Extensions}

\end{document}

在“扩展”部分中，我想使用相同的样式引入另外两个假设，但我想将它们标记为假设 1' 和假设 2'。我该怎么做？

答案1

您可以按照与假设构造类似的方式定义一个新环境，但通过更新命令来重新定义标签的打印，\the...其中...是相应的计数器名称：

\documentclass[12 pt,a4paper, oneside, openany, notitlepage]{article}

\usepackage{amssymb,xcolor}
\usepackage{mathtools}
\usepackage{amsthm}
\usepackage{amsfonts}

\newtheoremstyle{mystyle}% name
{\topsep}% Space above
{\topsep}% Space below
{\normalfont}% Body font
{}% Indent amount
{ \color{red}}% Theorem head font
{.}%Punctuation after theorem head
{.5em}%Space after theorem head
{}% theorem head spec
\theoremstyle{mystyle}
\newtheorem{assumptionex}{Assumption}
\newenvironment{assumption}
  {\pushQED{\qed}\renewcommand{\qedsymbol}{$\bullet$}\assumptionex}
  {\popQED\endassumptionex}
\newtheorem{assumptionexp}{Assumption}
\newenvironment{assumptionp}
  {\pushQED{\qed}\renewcommand{\qedsymbol}{$\bullet$}\assumptionexp}
  {\popQED\endassumptionexp}
\renewcommand{\theassumptionexp}{\arabic{assumptionexp}$'$}

\begin{document}
\section{Main}
\begin{assumption}
Blah
\end{assumption}

\begin{assumption}
Blah2
\end{assumption}

\section{Extensions}
\begin{assumptionp}
  Blahh
\end{assumptionp}

\begin{assumptionp}
  Blah22
\end{assumptionp}
\end{document}

具体来说，我定义了一个新定理assumptionexp和一个新环境assumptionp，然后重新定义了\theassumptionexp在数字上放置一个素数。
