Alignment problem with a mathematical equation in a presentation in beamer
I think the equation could benefit from a couple of additional line breaks.
\documentclass{beamer}
\usetheme{Antibes}
\usepackage{amsmath, amsthm, amssymb}%,amsfonts}
\newtheorem{rules}{Rule}

Addendum, inspired by a detail in @Bernard's parallel answer: If <
and >
do not denote "less than" and "greater than" and, instead, are supposed to be interpreted as angle brackets (\langle
and \rangle
, respectively, in TeX parlance), it would be better to combine rows three and four of the answer shown above into a single line:

\newtheorem{rules}{Rule}
\usepackage{graphicx}
\usepackage[utf8]{inputenc}

\int_{c_1-i\infty}^{c_1+i\infty}\frac{dz_1}{2\pi i}
\dotsm
\int_{c_J-i\infty}^{c_J+i\infty}\frac{dz_J}{2\pi i} \\
&\qquad\times
\langle z_1 + \dots + z_J - \alpha\rangle
\,A_1^{z_1}\dotsm A_J^{z_J}
\,\Gamma(-z_1)\dotsm\Gamma(-z_J)\,.
\end{split}
\end{equation}
\end{rules}
\end{frame}
\end{document}
I would go for a multline
environment. Unrelated: don't load packages twice, and also, if you load amssymb
, needless to load amsfonts
.
