Hi Charles,

You have a fair amount of flexibility when writing a paper, and almost
all papers take some facts for granted.  Your paper should make it
clear exactly which facts you assume, give references for these facts,
and then explain clearly and correctly how to deduce your result from
them.  I will post this message to the web site, hope its ok.
