I would like to use the package isomath (to force slanted capital Greek letters in mathmode) in beamer slides.

Beamer replaces the standard mathmode font with a sans-serif one. However, when using isomath with it, the slanted capital Greek letters appear with the same Serif font used in normal TeX documents. How can I obtain slanted sans-serif capital Greek letters that match the rest of the mathmode font used in Beamer?


I like $\Pi$


enter image description here

The \Pi here is rendered using a serif font that does not match the rest of the document.


Try with OMLmaths* option.

I like $\mathsf{\Pi}$ and $\mathit{\Pi}$
  • This works, but conflicts with \usepackage[T1]{fontenc}. I disabled it anyway. – Federico Poloni Mar 15 '12 at 8:55

    I get error: Package keyval Error: OMLmaths* undefined. Any idea? – Pygmalion Jul 17 '17 at 11:15
  • Why does this only appear to work for Π? I tried with \mu and \mathsf{\mu} and just got the standard mathematical serif µ. – gen-ℤ ready to perish Apr 27 '20 at 6:04

The documentation of isomath tells you that there are not many sans serif math fonts available:




I get a slanted Pi.

You can also try \usepackage{cmbright}.

  • But this would have the side effect of changing the math font for the rest of the document, wouldn't it? – Federico Poloni Mar 14 '12 at 21:51
  • @FedericoPoloni Yes. I don't find the Arev fonts so bad. – egreg Mar 14 '12 at 22:15
  • Is it possible to use cmbright for math only? I find arevmath too heavy, plus \Phi is ugly. – Pygmalion Jul 22 '17 at 14:33
  • @Pygmalion I think you can – egreg Jul 22 '17 at 15:48
