Я добавил символ ромба в конец моей теоремы (и других сред):
Однако когда я использую какую-либо отображаемую математику в конце теоремы, ромб устанавливается слишком низко:
Есть ли способ поднять алмаз?автоматическито есть он выровнен (или почти выровнен) с концом математического выражения? Что-то вроде этого (я использовал \tag*{\diamond}):

\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!

Вам нужны \qedhereслучаи, когда символ QED должен появиться на математическом дисплее или в конце списка ( enumerateили itemize).
Однако, выне должениспользование $$: см.Почему \[ ... \] предпочтительнее, чем $$ ... $$?. Здесь не просто «предпочтительно», аключевой. Любая стандартная amsmathсреда отображения принимает \qedhere.

When I use math mode correctly, the position of the $\diamond$ is perfect
