# how to render angle brackets with less spacing?

this code

$X = <X_1 ...,X_n>$


gives

how to have angle brackets render like this

use

$X = \langle X_1, \dots, X_n \rangle$

• @whnlp < and > in math mode are regular relational symbols. You must use \langle and \rangle, respectively. Oct 24, 2019 at 13:28
• It is very useful to use \ldots instead of ... Regards. Oct 24, 2019 at 14:07
• Or even (semantically) better: \dotsc (AMS) for "dots after comma". Oct 24, 2019 at 14:53
• @ivankokan In this example \dots can be used, instead of \dotsc; the result is the same in this case. See $x_1, \dotsc, x_n$ vs. $x_1$, $\dots$, $x_n$. Also for \dotsc the package amsmath is needed. Oct 24, 2019 at 15:40
• see tex.stackexchange.com/questions/122491/difference-of-the-dots for a comparison of the \dots* variants Oct 25, 2019 at 10:46

Another option it is to use bracket package. Here I'm putting a MWE with the fonts newtxtext (Times New Roman) for the text and newtxmath for mathematical symbols of your image.

\documentclass[a4paper,12pt]{article}
\usepackage{newtxtext,newtxmath}
\usepackage{braket}
\usepackage{blindtext}
\begin{document}
\blindtext
$X=\braket{X_1,\ldots,X_n}$
\blindtext
\end{document}
