Math & Science ⇒ Itemized List within a Theorem Environment

[thedoctor818]

Hello all,

I am typesetting some math notes, and have the following problem. I am using an itemized list within a theorem environment as follows:

Code: Select all

\begin{thm}
\begin{itemize}
\item $P \imp Q \equiv (\neg Q) \imp (\neg P).$
\item $P \imp Q \not \equiv Q \imp P.$
\end{itemize}
\end{thm}

However, every time I run LaTeX, I get the first item on the same line as the theorem title. I want the first item to be below the heorem title, but am not sure how to fix this. Help please. Thanks.

By now you should know that a proper minimal example is essential for instant help in such cases. Nobody is motivated to build one just to test possible solutions for your problem.

Of course, Thorsten, you are absolutely correct. I must apologize for my lack of a MWE here--and my late posting as well. I have now a fix to the problem, for anyone else who may be interested--and I hope (and please correct me if I am wrong) that it fits the MWE ``model.''

Code: Select all

\documentclass[12pt,a4paper,oneside]{report}
\pagestyle{myheadings}
\usepackage{amsmath,amssymb,amscd,amsthm,amstext}

\newtheorem{thm}{Theorem}
\def	\imp	{\Rightarrow}

\begin{document}
\title{Real Analysis Notes.}
\author{The Doctor.}
\date{\today}
\maketitle

\begin{thm}
\begin{itemize}
\mbox{}
\item $P \imp Q \equiv (\neg Q) \imp (\neg P).$
\item $P \imp Q \not \equiv Q \imp P.$
\end{itemize}
\end{thm}

\end{document}

Merely the ``addition'' of the \mbox was sufficient enough to move the first line of the statement of the theorem to the line below the ``actual'' numbering of said theorem. Again, I apologize for not following this rule here, and hope to do better in future when asking for help.

Another solution is to put an \hfill right after the beginning of the theorem like environment:

Code: Select all

\documentclass[12pt,a4paper,oneside]{report}
\pagestyle{myheadings}
\usepackage{amsmath,amssymb,amscd,amsthm,amstext}

\newtheorem{thm}{Theorem}
\def    \imp    {\Rightarrow}

\begin{document}
\title{Real Analysis Notes.}
\author{The Doctor.}
\date{\today}
\maketitle

\begin{thm}
\hfill
\begin{itemize}
\item $P \imp Q \equiv (\neg Q) \imp (\neg P).$
\item $P \imp Q \not \equiv Q \imp P.$
\end{itemize}
\end{thm}

\end{document}
