Math & Science ⇒ Two line under \inf

[avidanium]

Hello,

I have the following line:

$$\mathbf{h}_{se}(X)=\inf_{\pi:Y\rightarrow X\,\, \mathrm{symbolic}\,\mathrm{ext.}}
\mathbf{h}_{top}(Y)$$

I would like

\mathrm{symbolic}\,\mathrm{ext.}

to appear one line below

\pi:Y\rightarrow X

I tried using \\. However it doesn't work. Any help would be grealy appreciated!

Thank you.

Ron

Hi Ron,

welcome to the board!
Use \substack of amsmath, and \[ ... \] instead of $$ ... $$:

Code: Select all

\documentclass[a4paper,10pt]{article}
\usepackage{amsmath}
\begin{document}
\[
 \mathbf{h}_{se}(X)=\inf_{\substack{\pi:Y\rightarrow X\\
    \mathrm{symbolic}\,\mathrm{ext.}}}\mathbf{h}_{top}(Y)
\]
\end{document}
