When using \hat{}
, \tilde{}
and \bar{}
in formulas while also using the beamer
-package, instead of a bar over the sign I want to use a \Phi
is drawn, and instead of a hat over the letter a \Theta
is drawn. Why does that happen, and how can I fix that?
Minimal example:
\documentclass{beamer}
\usepackage{fourier}
\begin{document}
\begin{frame}
\frametitle{Some math in beamer}
\begin{equation}
\label{eq:1}
\hat A \neq A
\end{equation}
\end{frame}
\end{document}

I am no font expert, but it looks like there is a problem with the sans serif math font and
fourier
. A workaround would be to add\usefonttheme{professionalfonts}
. To cite from the beamer user guide:
