I have a problem and I can not figure it out,
Let c be a fixed constant, . Then if and only if . In particular, if the last series converges for one value of c, it converges for all values of c.
I appreciate any help.

But (counting the number of integers that are less or equal to |X|/c)
and since , you can conclude.
If you think it's not correct, just tell me, because I just wrote this, I don't know if it's a correct proof...
