I am making some slides for a presentation. I am copying parts of a texfile which I made earlier. The \emph{} command is not working in beamer (even though it is working in my original texfile).

For example, this code which is working in the original file is not working in beamer:

\begin{theorem}
{
 |\emph{Gal}(L|K)|=[F:K]
}
\end{theorem}

But this is working:

\begin{theorem}
{
 |Gal(L|K)|=[F:K]
}
\end{theorem}

But the 'Gal' is italic (I want it to be straight).

    By default, \emph works without problem within beamer. Can you provide a minimal example that replicates this problematic behaviour? – Werner Apr 26 '17 at 05:55
  • @Werner I edited the question. I have given the code in my question. – learning_math Apr 26 '17 at 06:34

    @learning_math: I should have been a bit more specific. Please read I've just been asked to write a minimal example, what is that? – Werner Apr 26 '17 at 06:38
  • In beamer this is a little tricky because of the fonts, so \mathrm might end up wrong. Since this is clearly a function I'd use \operatorname if this is just a one of. Why is his math not in math mode? – daleif Apr 26 '17 at 06:46
  • @Schweinebacke \text should never be used like that even in beamer. So many users misuse this macro, we don't need another answer misusing it. – daleif Apr 26 '17 at 07:14
  • @Schweinebacke it is clearly a math function which is why I suggest operatorname. Then the OP can also learn why | is not suppose to be used to mark the absolute value (too large spacing) – daleif Apr 26 '17 at 07:22

    @Schweinebacke in any case, theorems in beamer is in italic, so \text will be italic no matter how the OP writes it, math or not. Here the issue is just that \emph does not do anti-italic in an italic context. – daleif Apr 26 '17 at 09:38
  • The question cited in closing this question does not answer the question asked. I have encountered this same behavior. – Dan Fox May 23 '22 at 17:06
