On a queer binomial sum
R. Denk and R. Warlimont
Abstract. In this paper the binomial sum
is investigated. It turns out that the behaviour of this sum if n tends to infinity depends on the parameter r and changes dramatically at the values r=1 and r=2. In particular, for r greater or equal to 2 we obtain an oscillatory behaviour while for r<2 the sequence Sn(r) is monotonous at least for large values of n.
