Document Classes ⇒ mathbb does not work in beamer

[fenghedo]

Hi all,

I could not find out why the following code does not show $K$ in mathbb format. In fact, it shows a blank space in place of $K$:

Code: Select all

$k\in \alert{\mathbb{K}}$

I did include amsmath, amssymb. What could be wrong?


Thanks in advance.

I think perhaps you need to provide more information.

The minimal code:

Code: Select all

\documentclass{beamer}
\begin{document}
\begin{frame}
$k\in \alert{\mathbb{K}}$
\end{frame}
\end{document}

works for me, though I get some warnings.

Provide your own minimal example where it doesn't work. (Or if the above doesn't work you, try updating your packages, or provide details of your system.)
