math-modespacing
I posted an answer on math.se here and in there I used double dollar mode. Now in that mode, I had
\bigwedge^ \hspace{1mm} k V
but upon rendering it looks weird like
How can I bring the k closer to the big wedge so that it looks more normal like in single dollar mode? In single dollar mode, we have $\bigwedge^k V$ looking a lot more natural.
These two ways should work also in ConTeXt:
$\displaystyle\sum_{i=1}^n a_i$
$\sum\limits_{i=1}^n a_i$
Probably the second form is preferable, although I usually advise not to put limits above and below in in-line math formulas.
The text asterisk is raised, while the math asterisk is used for denoting an operation.
You can use \mbox{*} or \text{*} (if you load amsmath).
However, in general $Q^{*}$ is preferred.
You can get the behavior automatically:
\documentclass{article}
\usepackage{amsmath}
%%% magic code starts
\mathcode`*=\string"8000
\begingroup
\catcode`*=\active
\xdef*{\noexpand\textup{\string*}}
\endgroup
%%% magic code ends
\begin{document}
$a^{\ast} Q*$
\end{document}
I've added \ast that is the usual math asterisk for a comparison.
I'd recommend using the first form.
