一种函数的误差项及其均值估计

On the estimates of the error-term of certain function

对无平方因子数k ,对函数δk(n) =max{t∈N ,t|nand (t,k) =1 }的r(大于 1的自然数 )次方的误差项及其均值估计进行了研究 .

For a fixed natural square-free number k, the arithmetical function δ k(n)=max{t∈N,t|n and (t,k)=1} was defined and the estimation of the error-term of δ n(n)′s r -th power was studied.
