- Aug 1, 2007I have to say, I have a lot of trouble following any

argument that uses a modulus of 1. Could you use more

words, more generalized equations, describe more

specifically where your special cases arise, and maybe

outline the overall idea? The conjecture itself is

not at all clear to me. I don't understand the /

notation you're using.
