| below is a document that fails with teTeX-beta 20020530 (unfortunately I

| problems with \mathfrak and AMSfonts since the text
| [2002/01/19v2.2gAMSfontdefinitions] appears in the middle of the matrix.
That seems to be a genuine AMSfonts bug, and as such has nothing to do
with teTeX. FWIW, I see the same problem with teTeX beta-20021029.
The first occurence of \mathfrak triggers the loading of a font
description file. This happens within a matrix environment, and
that environment (like so many AMSmath environments) is quite
complex. I guess it reads its contents and tries to expand macros
along the way, and that plays havoc with the file inclusion.
A workaround is to use \mathfrak before you get to the matrix
environment. For example, use it in a throwaway box:
\setbox0\hbox{$\mathfrak{a}$}
(before \begin{document} is fine). Then the problem goes away.
But you might wish to report this to the AMSfonts maintainers as well.
