Is there a way to prevent \MakeUppercase from affecting in-text equations? In this example, abc should change to ABC, but n should be left as it is.
\documentclass{article}
\begin{document}
\MakeUppercase{abc $n$}
\end{document}
The following works for individual characters, but I would like something more general.
\documentclass{article}
\begin{document}
\newcount\mycount
\mycount\mathcode`n
\MakeUppercase{abc $\mathchar\mycount$}
\end{document}
\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{gather*}
\mbox{\scriptsize%
$A = \begin{bmatrix} a & b & c \\ d & e & f \\ g & h & i \end{bmatrix}$}\\
A = \begin{bmatrix} a & b & c \\ d & e & f \\ g & h & i \end{bmatrix}
\end{gather*}
\end{document}
The text along path decorations works by placing the text character for character. In your case, it tries to place the characters $, t, \rightarrow, t, _, 0 and $ on their own. This will lead to many errors ($ without a closing $, math-mode stuff in text-mode).
You will need to split the “text” up in its contents (the spacing provided by math-mode will be lost but this decoration isn’t made for that anyway).
\documentclass[tikz,border=5pt]{standalone}
\usetikzlibrary{decorations.text}
\tikzset{
text deco/.style={
postaction={decorate, decoration={text along path, #1}}}}
\begin{document}
\begin{tikzpicture}
\draw[
text deco={raise=5pt, text align={align=left, left indent=11em},
text={$t$} {$\rightarrow$} {$t_0$}},
text deco={raise=5pt, text align={align=left, left indent=15.5em},
text={$t$} {$\rightarrow$} {$t_0$}},
text deco={raise=-5pt,
text=|\color{gray}|........................%
|+\bfseries|........................%
|\color{blue!50}|.............................................}
]
(0,0) sin (1,1) cos (2,0) sin (3,-1) cos (4,0) sin (7,-1);
\end{tikzpicture}
\end{document}

The
textcasepackage was already mentioned. But if you are forced to stay with an unchanged\MakeUppercasefor some reason then you still have the poor man's choice of "hiding" the math:The
\protectis needed as\MakeUppercasein LaTeX is essentially an\edefthat only stops expanding at\protect.Or the alternative with eTeX which has protection at the macro definition level:
