Page Layout ⇒ Math environment within a list.

[lucia_]

Hi everyone,

I am writing an essay and I am using amsthm to create "claim" and "proof" math environments. Usually when one uses a "proof" environment, Latex creates an empty line before the proof. For example:

Code: Select all

Code, edit and compile here:

1
2
3
4
5
6
7
8
9
10
11
12
\documentclass{report}
\usepackage{amsthm}
\theoremstyle{remark}
\newtheorem{claim}{Claim}[chapter]
\begin{document}
\begin{claim}
This is a claim.
\end{claim}
\begin{proof}
This is a proof.
\end{proof}
\end{document}

I wanted to remove this line, so I did the following:

Code: Select all

Code, edit and compile here:

\documentclass{report}
\usepackage{amsthm}
\theoremstyle{remark}
\newtheorem{claim}{Claim}[chapter]
\newenvironment{claimproof}
  {\vspace{-1pc}\proof}
  {\endproof}
\begin{document}
\begin{claim}
This is a claim.
\end{claim}
\begin{claimproof}
This is a proof.
\end{claimproof}
\end{document}

However, I've noticed that when I am within an enumerate environment, it no longer works:

Code: Select all

Code, edit and compile here:

\documentclass{report}
\usepackage{amsthm}
\usepackage{enumitem}
\theoremstyle{remark}
\newtheorem{claim}{Claim}[chapter]
\newenvironment{claimproof}
  {\vspace{-1pc}\proof}
  {\endproof}
\begin{document}
\begin{enumerate}
    \item Hello. This is some text in a list. Hello hello. This is some text in a list. Some text in a list. ajsdhsdkfjhsdkfjashkdfjdshkf.
    \begin{claim}
    This is a claim.
    \end{claim}
    \begin{claimproof}
    This is a proof.
    \end{claimproof}
\end{enumerate}
\end{document}

Does anyone know how to keep that space before the proof removed, even when I am within an enumerate environment?

[Ijon Tichy]

This is the paragraph separation, that is the default of enumerate environments. You are already using package enumitem. So you could try \begin{enumerate}[parsep=0pt] or \begin{enumerate}[nosep]. For more information see the enumitem manual.

Hi Ijon,

That worked wonderfully.

Thanks so much for your help! :)
