我有一份文件，其中的证明有时在与陈述相关声明不同的页面上开始。
是否可以强制这样（除非权利要求的陈述超过一页）证明总是从陈述权利要求的页面开始？
例子：
LaTeX Code:
%% LyX 2.2.0dev created this file. For more info, see http://www.lyx.org/.
%% Do not edit unless you really know what you are doing.

您可以使用needspace（但我根本不知道如何使用 LyX 来做到这一点）。

答案2
答案在@Christian Hupfer 的评论中。
您提到使用 lyx，因此您需要在声明启动小页面之前添加 ERT。
\begin{minipage}[]{1 \textwidth}
在你关闭小页面的证明之后会出现一个 ERT：
\end{minipage}
确保您的 ERT 始终处于“标准”环境中。
有关 minipage 及其使用的更多信息，请在 ctan 中查找，或查看在这个网站上
另一种方法是使用samepage：在声明前添加 ERT
\begin{samepage}
证明完毕后
\end{samepage}
正如@Christian Hupfer 所说，minipage可能不会将索赔和证据放在您想要的位置，更改小页面中的选项[...]或使用samepage可能会解决您的放置问题
