# Is there a “small cap” version of greek symbols out there?

I need to use two versions of the Omega greek letter in the same equation, but I don't want to use uppercase and lowercase (as the latter looks like a w). Is there a way to differentiate between the two uppercase Omega characters (perhaps with an equivalent to small caps for latin characters)?

There's a text command in package tipa called \textscomega which seems to do what you want.

You can define

\newcommand{\scOmega}{\text{\textscomega}}


and use \scOmega in your document as in the following example:

\documentclass{article}
\usepackage{amsmath}
\usepackage{tipa}

\newcommand{\scOmega}{\text{\textscomega}}

\begin{document}
\begin{equation*}
\Omega\neq\scOmega
\end{equation*}
\end{document}


Output

If you don't want to load the tipa package entirely, you can load fontenc with the option T3 (needed for tipa symbols) and declare

\DeclareTextSymbolDefault\textscomega{T3}


MWE:

\documentclass{article}
\usepackage{amsmath}

\usepackage[T3,T1]{fontenc}
\DeclareTextSymbolDefault\textscomega{T3}

\newcommand{\scOmega}{\text{\textscomega}}

\begin{document}
\begin{equation*}
\Omega\neq\scOmega
\end{equation*}
\end{document}
