定理的替代编号

我正在使用thmtools作为前端，amsthm并且我有一个如下的定义环境。

\declaretheorem[
    style=mydefinitionstyle,
    name=Definition,
    numberwithin=chapter
]{definition}

我想要的是另一个环境，比如说称为definitionAlt，它将用于给出刚刚给出的定义的另一个定义，即，它使用与刚刚给出的定义相同的数字/计数器，但添加了“a”（或“b”或其他），而不增加计数器，并且交叉引用仍然有效。

\begin{definition}
\label{def:main_definition}
This is a definition which is numbered 1.1
\end{definition}

\begin{definitionAlt}
\label{def:alt_definition}
This is an alternative definition to the preceding one, which is automatically numbered 1.1a
\end{definitionAlt}

我见过类似的问题，例如 当编号完全是手动的时候，排版定理等的最直接的方法是什么？

它进行一些手动定理编号，但我找不到完全符合我要求的答案。

有人有什么建议吗？

答案1

\documentclass{report}
\usepackage{thmtools} 
\declaretheorem[
    style=mydefinitionstyle,
    name=Definition,
    numberwithin=chapter
]{definition}

\declaretheorem[
    style=mydefinitionstyle,
    name=Definition,
    numberwithin=definition,
]{definitionAlt}
\renewcommand\thedefinitionAlt{\thedefinition\alph{definitionAlt}}

\begin{document}
\chapter{Testing Alternate Definitions Counter} 
\begin{definition}
\label{def:main_definition}
This is a definition which is numbered 1.1
\end{definition}

\begin{definitionAlt}
\label{def:alt_definitiona}
This is an alternative definition to the preceding one, which is automatically numbered 1.1a
\end{definitionAlt} 

\begin{definitionAlt}
\label{def:alt_definitionb}
This is an alternative definition to the preceding one, which is automatically numbered 1.1b.
\end{definitionAlt} 

\begin{definition}
\label{def:another_main_definition}
This is a definition which is numbered 1.2.
\end{definition}
And, of course, I can refer to my second alternate definition, the definition \ref{def:alt_definitionb} and my another definition, the definition \ref{def:another_main_definition} quite well!

\begin{definitionAlt}
\label{def:new_alt_definitiona}
This is an alternative definition to the preceding one, which is automatically numbered 1.2a.
\end{definitionAlt} 

begin{definition}
\label{def:yet_another_main_definition}
This is a definition which is numbered 1.3.
\end{definition}
\end{document}

谢谢马可·丹尼尔感谢他的帮助！
