Abstract

Let b > a > 0. We prove the following asymptotic formula

n0|{x/(n+a)}-{x/(n+b)}|=2πζ(3/2)cx+O(c2/9x4/9),\sum\limits_{n \geqslant 0} {\left| {\left\{ {x/\left( {n + a} \right)} \right\} - \left\{ {x/\left( {n + b} \right)} \right\}} \right| = {2 \over \pi }\zeta \left( {3/2} \right)\sqrt {cx} + O\left( {{c^{2/9}}{x^{4/9}}} \right),}

with c = ba, uniformly for x ⩾ 40c 5(1 + b)27/2.
