General ⇒ Conflict between amsmath and beamer?

[curiouslearn]

Is there a known conflict between some commands between amsmath and beamer? I am trying to use the command pmatrix in a slide. I do get the desired matrix, but there are many errors thrown out during compilation. I am attaching both the code and the errors.

Thank you for any clarification.

Code: Select all

\documentclass{beamer}
\usepackage{amsmath}

\setbeameroption{show no notes}
\mode<presentation> {
\usetheme{Warsaw}
\setbeamercovered{transparent}
}
\setbeamertemplate{navigation symbols}{}
\setbeamertemplate{footline}{}

\title{Title}
\author[Author names]{Author name}

\institute[institute name]
{\inst{}
Department of Beamer\\
Institute of Technology\\}
\date{}

\begin{document}

\begin{frame}
	\titlepage
\end{frame}
   
		\begin{frame}{Slide Title}
				\begin{itemize}
				    
					\item Technology:
					           \begin{equation*}
								  
					           	  	\begin{pmatrix}
										$p_{00}$ & $p_{01}$ \\
							   			$p_{10}$ & $p_{11}$
									\end{pmatrix}
									 
					           \end{equation*}                                          
                 
					\item Another item
				\end{itemize}			
		\end{frame}		  
\end{document}              

The errors when trying to compile the above:

[phi]

The contents of pmatrix are already in math mode, so you leave the math mode in every cell, but the subscripts don't work in text mode. Simply remove all dollar signs inside the pmatrix environment. Furthermore, be aware of paragraph breaks, they are inserted whenever you input an empty line, which is not supported everywhere, especially in math environments. So please remove all empty lines between \begin{itemize} and \end{itemize}, unless you explicitly want paragraphs there.

Thanks phi. I thought I had tried it even without the dollar signs...apparently I had not. I removed the blank lines and the $ signs and it worked great.

Thanks again.

Hi,

if you want to remove the beamer warnings have a look at: How to get rid of those beamer warnings.
