Limit controls must follow a amth operator: proper \lim usage?
kane
I have a small problem, which probably can be solved in a second, but
I didn't find useful information on the web.
I have a working math doc, but adding the following code into some
text throws the above mentioned error:
$\lim_{n \to \infty}$
I just can't figure out, why. I found two sources which both told me
to use lim in that way. Looking for the error gave me some other
possibilities, like adding \limits_{...} or using \mathop{} but using
them gives the same error.
Can somebody help me?

full minimal example and a quote of the error might help

You (or the class you are using) have redefined \lim in a wrong way,
probably to get the limits under the "lim" also in in-line math mode
(which is quite dubious, from a typographical point of view).

solved it by just writing "lim" without preceding backslash, which is
fine, because this document is only for me anyway. I was just
wondering whether I use the lim-operator just in a wrong way.
but here are the settings i use (i copied them over from some other
source):

nath seems to be very offended
do you need the nath package?
Enrico Gregorio
In the log you find
Nath as of 21 March 2003
Implementing NAtural maTH notation
AmSLaTeX detected.
Do not expect too much from this combination.
Consult Nath Guide if things go bad.
The guide to Nath doesn't tell anything about this. Forget
about Nath.

Still further reduced:
\documentclass{article}
\usepackage{amsmath}
\usepackage{nath}
\begin{document}
$\lim$
\end{document}
(Also $\to$ alone throws two errors.)
So, in fact, it has nothing whatsoever to do with the
limit controls. In fact, nath redefines the primitive
$-sign as well as \mathop. Either of these has the
protential to throw almost any other math package into
convulsions.
[I see that $\lim_{n\to\infty}$ at least produces the
correct output. After three errors.]
