I have began using the Minion Pro series of fonts and compiling with XeLaTeX. However, despite the typeface changing, I still have the same CM Modern Math fonts. Do any of you have a good suggestion for a good math font that works with Minion Pro?

I have used usepackage{mathastext} and the italic varient usepackage[italic]{mathastext} but the 'f' in math mode is very awkward and too close to the parethesis. The code that produces this effects is:

documentclass{article}

usepackage{fontspec}

defaultfontfeatures{Mapping=tex}

setmainfont{Minion Pro}

usepackage[italic]{mathastext}



begin{document}

This is the standard Minion Pro Fontldots My issue is with the 'f' in italic math mode. It needs more space. For example:



begin{equation}

f(x) = x^2 + f(n-1) 

end{equation}



end{document}

Is there a better option than usepackage{mathastext}? or is there a way to adjust this minor issue? I have never been able to get usepackage{MnSymbol} working (I keep getting a Command mathdollar already defined error) and Minion Math is well... pricey.

I suggest to use the MinionPro package. It works under XeLaTeX and pdfLaTeX. It is part of the Font Pro package available from https://github.com/sebschub/FontPro. Follow the instructions there to install it.

The following MWE

documentclass{article}



usepackage{MinionPro}



begin{document}

This is the standard Minion Pro Fontldots My issue is with the 'f' in italic math mode. It needs more space. For example:



begin{equation}

f(x) = x^2 + f(n-1) 

end{equation}



end{document}

yields

Another solution is to use the MnSymbols package. To avoid the problem with the mathdollar already defined error one can use the following workaround.

usepackage{fontspec}

usepackage{etoolbox}



defaultfontfeatures{Mapping=tex}

setmainfont{Minion Pro}



usepackage{MnSymbol}



% the next line makes the definition of mathdollar from MnSymbol void.

undefmathdollar 



% the next 3 lines reinstate the definition of mathdollar from MnSymbols 

% at the begin  of the document

makeatletter

AtBeginDocument{DeclareRobustCommand{mathdollar{Mn@Text@With@MathVersion{textdollar}}}

makeatother

André Miede, the author of classicthesis - which uses Minion Pro, recommends the Euler Math font to use with the latter one:

"[...] loads the awesome Euler fonts for math." [emphesis mine]

(from the classicthesis documentation, page 6)

According to the German Wikipedia article there is a Minion Math font by Typoma, specifically designed for Minion Pro.
