These problems used to reside on a wiki hosted by the American Institute of Mathematics, but it was drawing too much spam so was taken down.  Since people still appear to be referring to them, I have set up this webpage with pdf versions of the topic-specific drafts.  For specific comments or questions, please contact the author(s).  To submit or update a draft, please contact me (rscott at scu dot edu).
