一些定义和定理以 itemize 结尾。当我使用纯 amsthm 时，它看起来不错，但当我使用 thmtools+amsthm 时，它看起来很丑陋，定理下方有太多空间。我看不出我在 \declaretheoremstyle 中做错了什么。
有人可以帮帮我吗？
\documentclass{article}
\usepackage{amsthm}
%%%%%%%%%%% Uncomment to use pure amsthm %%%%%%%%%%%%
% \newtheorem{mytheorem}{Mytheorem}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%% Comment out to use pure amsthm %%%%%%%%%%
\usepackage{thmtools}
% Set all vertical spaces I know of to zero to illustrate issue.
\declaretheoremstyle[
spaceabove=0pt,
spacebelow=0pt,
headfont=\normalfont\bfseries,
notefont=\bfseries,
notebraces={(}{)},
bodyfont=\normalfont,
qed={},
headpunct={.}
]{mytheoremstyle}
\declaretheorem[style=mytheoremstyle, name=MyTheorem]{mytheorem}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{document}
\noindent
Text before theorem without indent for clarity.
\begin{mytheorem}
Here is my theorem with itemize inside it.
\begin{itemize}
\item My item A.
\item My item B.
\end{itemize}
\end{mytheorem}
\noindent
Text after the theorem without indent for clarity.
\begin{mytheorem}
Here is another theorem without any itemize inside it.
\end{mytheorem}
\noindent
Final text here without indent for clarity.
\end{document}

我认为这qed={}是添加了一行空格。如果你注释掉它，差异就会消失：
\documentclass{article}
\usepackage{amsthm}
%%%%%%%%%%% Uncomment to use pure amsthm %%%%%%%%%%%%
% \newtheorem{mytheorem}{Mytheorem}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%% Comment out to use pure amsthm %%%%%%%%%%
\usepackage{thmtools}
% Set all vertical spaces I know of to zero to illustrate issue.
\declaretheoremstyle[
spaceabove=0pt,
spacebelow=0pt,
headfont=\normalfont\bfseries,
notefont=\bfseries,
notebraces={(}{)},
bodyfont=\normalfont,
% qed={},
headpunct={.}
]{mytheoremstyle}
%
\declaretheorem[style=mytheoremstyle, name=MyTheorem]{mytheorem}
% \declaretheorem[name=MyTheorem]{mytheorem}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\begin{document}
