研究不等式α≤{x/p}〈α+R/p(p≤x)和0≤{x/p}〈α(p≤y)的解的个数问题,对前一不等式,当x^32/47+ε〈R〈x^1-ε时得到了解数的渐近公式;对后一不等式,将Saffari和Vaughan的渐近公式中y的下界从x^6/11+ε改进到x^ε.
The aim of this paper is to study the numbers of solutions of the inequalities α≤{x/p}〈α+R/p(p≤x)和0≤{x/p}〈α(p≤y). For the former inequality, we obtain an asymptotic formula for X^32/47+ε ( R 〈 x^1-ε. For the latter inequality, we obtain an asymptotic formula for x^ε≤ y 〈 x, which improves an classical result of Saffari and Vaughan.
