Concmath-otf package


Concrete-Math.otf’ is an Opentype version of the Concrete Math fontcreated by Ulrik Vieth in . concmath-otf.sty’ is a replacementfor the original concmath.sty’ package.


  • Concrete-Math.otf OpenType Math font
  • concmath-otf.sty style file: replaces concmath.sty for Lua/
  • concmath-otf.pdf Documentation in PDF format
  • concmath-otf.ltx source of concmath-otf.pdf
  • unimath-concrete.pdf Modified version of unimath-symbols.pdf showing available Concrete-Math symbols compared to
  •                LatinModern, STIXTwo, TeXGyrePagella and DejaVu.
  • unimath-concmath.ltx source of unimath-concrete.pdf
  • README.md (this file)


This package is meant to be installed automatically by Live, Mik, etc. Otherwise, the package can be installed under TEXMFHOME or TEXMFLOCAL, f.i. Concrete-Math.otf in directory texmf-local/fonts/opentype/public/concmath-otf/ and concmath-otf.sty in directory texmf-local/tex/latex/concmath-otf/. Documentation files and their sources can go to directory texmf-local/doc/fonts/public/concmath-otf/

Don't forget to rebuild the file database (mktexlsr or so) if you install under TEXMFLOCAL.

Finally, make the system font database aware of the Concrete-Math font (fontconfig under Linux).
