我在定理（和其他）環境的末尾添加了一個菱形符號：
然而，當我在定理末尾使用任何顯示數學時，菱形設定得太低：
有什麼辦法可以讓鑽石升起來嗎？自動地所以它與數學表達式的末尾對齊（或幾乎對齊）？像這樣的東西（我用過\tag*{\diamond}）：

\usepackage{amsmath}
\usepackage{dsfont}
%im using this font (in case it is important)

%this new commands let me end every statment of a theorem, remark or proposition with any symbol, in this case i'm using "$\diamond$"
\newcommand{\thmsymbol}{$\diamond$}
\newenvironment{thrm}{\begin{thrm1}%

{\popQED\end{thrm1}}
\newenvironment{remark}{\begin{remark1}%
\renewcommand{\qedsymbol}{\thmsymbol}\pushQED{\qed}}%
{\popQED\end{remark1}}
\newenvironment{prop}{\begin{prop1}%
\renewcommand{\qedsymbol}{\thmsymbol}\pushQED{\qed}}%
{\popQED\end{prop1}}
\begin{document}
\section*{So, my problem is the following.}
\begin{thrm} Every end of a theorem, proposition, remark etc, is marked with the symbol ``$\diamond$''.
\end{thrm}
\begin{remark}
As you can see, the diamond symbol is positioned immediately at the end of the sentence. I mean, it is just right here $\rightarrow\rightarrow\rightarrow\rightarrow\rightarrow$
\end{remark}
\section*{My problem is when I use math mode}
\begin{prop} When I use math mode, the position of the $\diamond$ is too low
$$\int_0^1 x \, dx = \frac{1}{2} \quad \text{i mean, it goes waaaay down: } \rightarrow\rightarrow\rightarrow\rightarrow\rightarrow\rightarrow\rightarrow \searrow $$
\end{prop}
My question is: \textbf{is there some way to get the diamond up, automatically?} aligned (or almost aligned) with the end of the math expression, something like this:
\begin{prop1} Here is Euler's formula
\begin{align*}
e^{ix} = \cos (x) + i \sin (x) \quad\quad \forall x \in \mathds{R} \tag*{$\diamond$}
\end{align*}
\end{prop1}
And I can continue without any problem, instead of dealing with:
\begin{prop} Here is Euler's formula
\begin{align*}
e^{ix} = \cos (x) + i \sin (x) \quad\quad \forall x \in \mathds{R}
\end{align*}
\end{prop}
\noindent Too much space between the math expression and the diamond symbol!
\end{document}
答案1
您需要\qedhereQED 符號必須出現在數學顯示中或清單末尾（enumerate或itemize）的情況。
然而，你不可以使用$$：參見為什麼 \[ ... \] 優於 $$ ... $$？。這裡不僅僅是“優選”，而是至關重要的。任何標準amsmath顯示環境都接受\qedhere。

\renewcommand{\qedsymbol}{\thmsymbol}\pushQED{\qed}}%
{\popQED\end{thrm1}}

\renewcommand{\qedsymbol}{\thmsymbol}\pushQED{\qed}}%

\end{thrm}
\begin{remark}

\end{remark}
\section*{My problem is when I use math mode}
\begin{prop}
When I use math mode correctly, the position of the $\diamond$ is perfect
\[
\int_0^1 x \, dx = \frac{1}{2} \qedhere
\]
\end{prop}
\end{document}
我只留下了文檔的相關部分。
