# Different display styles in math mode?

## Code:

\documentclass{article}
\usepackage{amsmath}
\usepackage{amssymb}
%\usepackage{mathabx}

\begin{document}

$\phi(\underbrace{r\cdots r}_{n-\text{veces}}) \qquad a\in A \qquad A\subseteq B \qquad\mathbb{Z}[i]$

\end{document}


## My question is:

Are there other packages that generate a similar effect \usepackage{mathabx}?

• Yes, MnSymbol also provides a new math symbol font, which would cause a similar effect of "changing the notation" slightly. – Werner Nov 4 '15 at 0:54
• ...but I don't know whether this answers your question. It still seems very broad to me. – Werner Nov 4 '15 at 1:05
• @Werner -- Your answer is very useful for me.Thanks – CarlosE Nov 4 '15 at 1:13

• There are several font packages that change the math font see e.g. tug.dk/FontCatalogue/mathfonts.html – Torbjørn T. Nov 4 '15 at 8:48
