LaTeX forum ⇒ Math & Science ⇒ Reduce space before and after a sum in an equation Topic is solved

[NELLLY]

Hello
I need to reduce the space before and after the sum in an equation to be placed within a text. This is the equation

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

  \documentclass[12pt]{article}
  \begin{document}
  texte.....$\alpha = \displaystyle\sum_{j=UCL+1}^{n}BIN(j, n, p_0)$....texte
  \end{document}

I used \! to reduce space but I didn't get good results.

Use \mathclap from mathtools (part of the mh bundle).

Code: [Select all] [Expand/Collapse] [Download] (untitled.tex)

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{mathtools}  % loads »amsmath«
 
\begin{document}
   \[
     \alpha =\sum_{\mathclap{j=UCL+1}}^{n} BIN(j,n,p_0)
   \]
\end{document}
