General ⇒ Undefined Control Sequence errors

[Danyon]

Hi (I'm new to this forum)

I've been sent a file from someone but when I try to compile it I get "undefined control sequence" errors. I have found the lines that are causing the errors, but I am not sure what the problem is.

I found that the original author was missing a \usepackage{mathrsfs} command which I have now added. This has reduced the number of 'undefined control sequence' errors to only one. I am assuming that there is another missing \usepackage command.

Code: Select all

\documentclass[notes=show]{beamer}

\usepackage{amsfonts}
\usepackage{amsmath}
\usepackage{mathpazo}
\usepackage{hyperref}

The section causing the problem is:

Code: Select all

\begin{equation*}
\Phi ( \tilde{m} ( \zeta ))=\displaystyle\sum_{j=1}^q\displaystyle\sum_{l=1}^r \display\sum_{n=r-1} \frac{1}{l!}\frac{1}{n!} \frac{\partial^{(l)}m}{(\partial z_j)^l} |_{z=\zeta} \frac{%\partial^{(n)}f}{(\partial z_j)^n}|_{z=\zeta}
\end{equation*}

Does anyone have any ideas on how to get rid of the undefined control sequence error? I am using MiKTeX 2.7 with Winshell 3.3.0.

Many thanks for your help.

Hi,

the problem comes from "\display" which is not a command and from a superfluous comment sign "%"; replace \display with \displaystyle and delete the superfluous sign:

Code: Select all

\begin{equation*}
\Phi ( \tilde{m} ( \zeta ))=\displaystyle\sum_{j=1}^q\displaystyle\sum_{l=1}^r \displaystyle\sum_{n=r-1} \frac{1}{l!}\frac{1}{n!} \frac{\partial^{(l)}m}{(\partial z_j)^l} \bigg\vert_{z=\zeta} \frac{\partial^{(n)}f}{(\partial z_j)^n}\bigg\vert_{z=\zeta}
\end{equation*}

I also extended the evaluation vertical lines.
