Sφ(x)= 6 π xlogx + Ox(logx)log 2x(1/3)n(4),并证明了(4)中的误差项为Ω(x),其中log 2表示重对数.􏼑􏼐􏼁一些相关的工作可以在[4,5]中找到。由于因子和函数σ(n)≠􏽐 d| nd在许多情况下具有与欧拉函数φ(n)相似的性质,考虑它与(3)的类比似乎是自然和有趣的。我们的结果如下。
Sφ(x) � 6 π x log x + O x(log x) log2 x ( 􏼁 (1/3) 􏼐 􏼑, (4) and also proved that the error term in (4) isΩ(x), where log2 denotes the iterated logarithm. Some related works can be found in [4, 5]. Since the sum-of-divisors function σ(n) ≔ 􏽐d|nd has similar properties as the Euler function φ(n) in many cases, it seems natural and interesting to consider its analogy of (3). Our result is as follows.
