研究了与D.H.Lehmer问题有关的两个求和估计问题,并利用特征的正交关系,将其转化为有关Gauss和及Dirichlet L-函数的求和式,同时结合原特征的性质与L-函数的均值定理得到两个有趣的渐近公式,表明所研究的数论函数具有较好的渐近分布性质.
Two new interesting arithmetical functions are introduced in this paper, and by using the mean value theorems of the Dirichlet L-functions and the properties of primitive character, some sharper asymptotic formulae are obtained.
