Abstract: | Let A be an infinite sequence of positive integers a1 < a2 <… and put , . In Part I, it was proved that . In this paper, this theorem is sharpened by estimating DA(x) in terms of fA(x). It is shown that limx→+∞sup DA(x) exp(?c1(logfA(x))2) = +∞ and that this assertion is not true if c1 is replaced by a large constant c2. |
