两个与Dedekind函数有关的误差项的新研究

NEW RESULTS ON TWO ERROR TERMS RELATED TO THE DEDEKIND TOTIENT FUNCTION

设ψ（ｎ）是Ｄｅｄｅｋｉｎｄ函数，则其中ａ，ｂ，ｃ均是常数，而Ｅ（ｘ），Ｒ（ｘ）是误差项，本文研究了Ｅ（ｘ）和Ｒ（ｘ）的某种加权的平方积分均值。

Let φ(n)be the Dedekind totieint function. It is known that where a ,b, c are constants,and E(x),R(x)are error terms.Two results on some kind of weighted mean squares of E(x) and R(x)are obtained in this paper.
