fontsmath-modesans-serif
I would like to change the sans serif math font to, say, Kurier, while keeping the roman font as the default. In other words, I'd like to change the font that is used with \mathsf whithout affecting the behaviour of the other math commands. Any suggestion?
Thank you in advance
The Arev font family has no standard way of scaling fonts, so we have to avoid loading the font description files; I just copied the contents of omlzavm.fd and modified it, adding a scaling factor. The computation of the scaling factor could be made automatic, but the .78 factor seems to be good.
\documentclass[a4paper, 10pt]{scrartcl}
\usepackage[T1]{fontenc}
\DeclareFontFamily{OML}{zavm}{\skewchar\font=127 }
\DeclareFontShape{OML}{zavm}{m}{it}{<-> s*[.78] zavmri7m}{}
\DeclareFontShape{OML}{zavm}{b}{it}{<-> s*[.78] zavmbi7m}{}
\DeclareFontShape{OML}{zavm}{m}{sl}{<->ssub * zavm/m/it}{}
\DeclareFontShape{OML}{zavm}{bx}{it}{<->ssub * zavm/b/it}{}
\DeclareFontShape{OML}{zavm}{b}{sl}{<->ssub * zavm/b/it}{}
\DeclareFontShape{OML}{zavm}{bx}{sl}{<->ssub * zavm/b/sl}{}
\DeclareMathAlphabet{\mathsf}{OML}{zavm}{m}{it} % not `n'
\begin{document}

You can easily map \mathsf to montserrat. But apart from some math in section titles I don't see why you would want to write e.g. the numbers as sans serif.
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[light,onlyrm]{kpfonts}
\usepackage[light,scale=0.85]{montserrat}
\usepackage[sf,uppercase]{titlesec}
\newcommand*\elseries{\fontseries{el}\selectfont}
\titleformat*{\section}{\sffamily\elseries\large}
\SetMathAlphabet{\mathsf} {normal}{T1} {Montserrat-LF} {l}{n}
\begin{document}
\section{Section Title}\makeatletter
A little piece of text, \textsf{with some sans serif parts}, and some math:
\begin{equation*}
e^{i\pi}+1=0
\end{equation*}
Plus some sans serif math:
\begin{equation*}
\mathsf{e^{i\pi}+1=0}
\end{equation*}
Good looking sans serif math:
\begin{equation*}
\text{\textsf{e}}^{\text{\textsf{i}}\pi} + \text{\textsf{1}} =
\text{\textsf{1}}
\end{equation*}
\begin{equation*}
\mathsf{e}^{\mathsf{i}\pi} + \mathsf{1} =
\mathsf{1}
\end{equation*}
\end{document}

Look in the file
kurier.styand you'll find the lines (not in the same places)that tell you how to do in your case. The first line reveals the font family internal name, the other two what's used for
\mathsf. So, addto your document preamble. The first declaration tells LaTeX that
\mathsfmust use Kurier, changing it into bold when the math version is bold.
