The work (``Permutation Polynomials modulo 2^w'') has been submitted to Academic Press for possible publication. Copyright may be transferred without notice, after which this version may no longer be accessible.

In spite of what this seems to imply, the agreement also gives permission to the author to post the final accepted form of the paper on his personal web server, and I will do so, if the paper is accepted. So don't worry that the paper will go away. (Well, this version may go away, but the final accepted version will be posted here.)
