For example, I'd like to do:

$Q^{r<1}$

but with the r<1 having a much smaller font size than the Q. Of course r<1 will naturally have a smaller size since it is a superscript, but I want to make it even smaller, without changing the size of Q.

I prefer a solution in LyX, but a TeX solution will do.

    Hmm, when I compile, the font size of r<1 is smaller than Q. What do you get?

  • Thanks kan and Torbjorn. kan you are right (I have edited my question to reflect this). May 5, 2013 at 13:47

    @Jubobs -- the cited question asks specifically how to make parts of an equation larger. this one is about making something smaller. $Q^{\scriptscriptstyle r<1}$ should do that, and i'm not sure a new user would know that. {i also don't think that it's a good idea.} May 5, 2013 at 15:58

    @Jubobs, @barbara beeton: I do not necessarily think that this is a duplicate question. The referenced duplicate explains how to make math text smaller in a systematic way, but it is possible that this question desires an "exception to the rule" kind of answer, given that the superscripted material is not a typical exponent. He may want to leave exponentiation the defaulte size, but for this kind of superscript change the size. Something like a $Q^{\scaleto{r<1}{.5ex}}$ from the scalerel package could achieve this.

If you really need to go smaller than scriptscriptsyle, you could use scalebox (but it's getting very small to read)

enter image description here

\documentclass{article}
\usepackage{graphicx}
\begin{document}


$Q^{r<1}$

$Q^{\scriptscriptstyle r<2}$

$Q^{\scalebox{.2}{$r<4$}}$

\end{document}

Method

  1. Insert math macro (from the menu or the "\foo:=" button on the toolbar)

    a. For Name type say "qp" .

    b. For TeX type exactly "\mathbb Q ^\scalebox{.5 {#1" The result should look like "Q\scalebox{.5}{#1}". This will be output in the LaTeX.

    c. For Lyx type say "\mathbb Q ^#1 _\circ". The result should look like "Q°#1". This will be displayed in Lyx.

  2. Go to Document Settings LaTeX Preamble and add "\usepackage{graphicx}".

  3. Write your document after the macro definition and use "\qp" wherever you want this tiny power of Q.

Notes

You are of course free to choose a different macro name as well as a different LyX part. I chose to use "_\circ" to clearly distinguish it from the usual "\mathbb{Q}".
