# [texhax] problem with a defined command

Fri Jan 17 16:06:55 CET 2014

I would guess that the arxiv checks to see if the sources compile and uses the abstract on the web page as is.
Leaving it to the uploader to verify that the abstract is ok online. In earlier version (without mathjax) that would make sense, the just display the abstract unprocessed. Seems they have just added the mathjax postprocessor at let it run on what ever they have always been using.

I do not know the details.

OK, so, having lied to my system as to what the file is called
and unpacked it, the abstract typesets perfectly, as does the
rest of the paper.  So I'm not sure what conclusions I am meant
to draw.  Was the author asked to submit the abstract separately,
and if so, did he fail to include all required macros, or does
the problem lie with the Arxiv system (i.e., can it process only
a subset of the commands used in the author's document) ?
