Text Formatting ⇒ Item Text of itemized List overlaps Proof Header

[Fibonacci]

Say I'm writing the proof of a long list of equivalences.
The usual way to do this is to prove that the first implies the second, the second implies the third, and so on. The obvious way to write that would be with itemize:

Code: Select all

\documentclass{article}
\usepackage{amsthm}
\begin{document}
\begin{proof}
\begin{itemize}
\item[$(a\Rightarrow b)$] This is the proof
\end{itemize}
\end{proof}
\end{document}

That, however, makes the $(a\Rightarrow b)$ text overlap the "Proof." header.

Leaving an empty line before the itemize to prevent that doesn't look acceptable, though.

How can I fix that, then?

For this purpose it is better to use a {description} environment.

Code: Select all

\documentclass{article}
\usepackage{amsthm}

\begin{document}
  \begin{proof}
    \begin{description}
    \item[$(a\Rightarrow b)$] This is the proof
    \end{description}
  \end{proof}
\end{document}

As you can see, your problem vanishes.

Thank you, that does exactly what I was looking for.
