hey, can we use supremum and infemum concept here?
Replacing by (for all n), you reduce the problem to the case where p=0. The proof for that case is given in this thread.
I actually have to solve this same problem, and I clicked on "this thread" but it just brought me to the general page of all the threads. I've been trying to find it but I'm not getting anywhere, is there a more specific location I can find the thread that solves this problem? Please help!!
