在定理/假设前缩进

Question

请参阅下面我尝试在 Assumption 行前添加缩进的示例。请参阅我在实际文档中使用的序言中的包。我读到 ragged2e 会消除缩进。即使我将其更改为\usepackage{tabularx,ragged2e,booktabs,caption}，\usepackage{tabularx}Assumption 之前也没有添加缩进。

known.}
\end{myassum}

\parindent30pt\begin{myassum}\label{asum_contro} \rm{The value of
$(A,B)$ are known.}
\end{myassum}

Please help me add an indent just before Assumption 1. I mean the
assumptions should start as a paragraph.
\end{document}

Answer 1

该ntheorem包提供了\theoremindent，必须在\ntheorem与\theoremindent\parindent, i.e. without{}` 对之前使用。

使用定理样式会更好。
