Is there a way to show \sum
limits partially in inline mode and partially in display mode?
I want to write:
\begin{equation}
\sum_{n=-\infty}^{+\infty} [...]
\end{equation}
but this way the lower limit is too wide, and I don't like it. So I was hoping to write something like this:
\begin{equation}
\sum_{-\infty}^{+\infty}\nolimits_{n} [...]
\end{equation}
to write the index n on the right side of the sum symbol, while the limits of the summation remain above and below.
Of course it doesn't work, LaTeX is pissed because there is a double subscript. Anyone knows if it's possible to do what I want to?

In this instance a better approach would be to use
mathtools
's\mathclap
, which provides a centred overlap in math mode. The centred overlap implies a zero-width box containing stuff that overlaps on the left and right:Sure
mathtools
also loadsamsmath
, but both these provide excellent tools in terms of typesetting mathematical content (and otherwise).To add multiple things under a math operator (like
\sum
), see How do you put multiple things under a limit?, which suggests\substack
(as I've done in the last horrible visual).
