I am wondering how can I ensure that an argument gets placed underneath \min when I use an align environment.
When I use math mode and write
\[
min_{x_1,\dots x_T}
\]
the {x_1,\dots x_T} is placed directly underneath min.
However when I use an align environment and write
\begin{align*}
min_{x_1\dots x_T}
\end{align*}
the {x_1,\dots x_T} is placed to the bottom left of \min.
The macro is \min, not min.
When you use \min in display mode (ie, within \[ \min_{<subscript>} \], or within the align environment), the subscript is placed underneath by default.
When you use \min in inline math mode (ie, with $\min_{<subscript>}$), then you need to
specify \displaystyle, or \limits to get the subscript underneath.
All four below produce:
\documentclass{article}
\usepackage{amsmath}
\begin{document}
Inline mode:
$\displaystyle \min_{x_1,\dots x_T}$
$\min\limits_{x_1,\dots x_T}$
\bigskip
Display mode:
\[ \min_{x_1,\dots x_T} \]
%
\begin{align*}
\min_{x_1\dots x_T}
\end{align*}
\end{document}

\documentclassand the appropriate packages so that those trying to help don't have to recreate it. – Peter Grill Mar 28 '12 at 01:58$...$in the first example instead of\[ ... \]? Or perhaps you just meant\mininstead ofmin? – Peter Grill Mar 28 '12 at 01:59
