Please reply to me directly ([EMAIL PROTECTED]) rather than to the
list, since the question is completely R-free and I'm simply asking
this list because there are so many clever and knowledgeable people
on it.
Suppose that n_i, i = 1, 2, 3, ... are positive integers, and that
k
lim SUM n_i^j = nu_j < infinity
k --> infinity i=1
for j = 1, 2, 3. Need it be the case that
k-1
lim SUM n_i * n_{i+1} exists?
k --> infinity i=1
I can neither prove this, nor come up with a counter-example.
Can anyone help me out?
cheers,
Rolf Turner
