Number Theory  value of the sum
Posted:
Nov 19, 2007 8:03 AM


Hi all, Let u range over integers with \omega(u)=2 (that means it has only two distinct prime dividers) and the grater prime divider is not bigger then y. What is the value of sum of 1/u? It should be more or less equal to (loglog y)^2 but I don't know why... If it helps: Sum of pprime <= x is more or less log log x ;) I would appreciate of kinds of help. Greetings Michal
