Thank you, Simon, this is an interesting paper! However, it's unfortunately not the one I was looking for; also, I remember better the problem: given a function (+) of two variables x,y, find a function p() such that p(x) + p(y) = p(x (+) y) Somehow they got from x (+) y = xy to p'(x) = 1/x and then integrated to get p = log. -- Mike Stay - metaweta@gmail.com http://math.ucr.edu/~mike http://reperiendi.wordpress.com
