Math & Science ⇒ subscripts in \mathbb font

[sasha]

Hi:

If I type $W_{\mathbb C}$, the subscript is too big.

If I type $W_{\tiny {\C}}$, I get a TEX warning (\tiny is not allowed
in math mode), but the actual page looks exactly as I want.

And if I try to use a macro, say, like that

\newcommand{\lc}{\tiny {\C}}

I even get an error message saying, again, that \tiny is not allowed
in math mode.

How can I ``legally'' get a subscript which looks like a small
$\mathbb C$ (i.e., something like what I get when I type
$W_{\tiny {\C}}$), but without warnings (I need to use this line a lot and
don't want to get hundreds of warning messages when I latex my file).

Thanks,

AB

You might want to try the \mathsmaller command from the relsize package. E.g.:

Code: Select all

\documentclass{article}
\usepackage{amsfonts}
\usepackage{relsize}
\newcommand{\lc}{\ensuremath{\mathsmaller{\mathbb{C}}}}
\begin{document}
$W_\lc$
\end{document}

I would say the final solution depends on whether the subscript is an index variable or a designator (like in the Boltzmann constant).

Code: Select all

\documentclass[11pt,a4paper,english]{article}
\usepackage[T1]{fontenc}
\usepackage[latin1]{inputenc}
\usepackage{babel}
\usepackage{amsmath}

\parindent0em

\begin{document}
  \[
    W_\textbf{C}
  \]

  \[
    W_{\boldsymbol{C}}
  \]
\end{document}

In both cases the amsmath package helps in formatting the subscript.

Sasha wants \mathbb not \mathbf, Thorsten.

Yes, of course. A small but important detail that I missed. But I can't comprehend the misbehaviour.

Code: Select all

\documentclass[11pt,a4paper,english]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{amsmath}
\usepackage{amssymb}

\begin{document}
  $W_\mathbb{C}$
  \[
    W_\mathbb{C}
  \]
\end{document}

The subscript appears as small as usual text. But perhaps this is just a matter of taste.
