引进了两个新的可乘函数U(n)和V(n),利用解析方法研究了∑n∈An≤xU(n)及∑n∈An≤xV(n)的均值分布性质,给出了两个较强的渐近公式,其中A表示所有无k+1次幂因子数组成的集合。所得结果表明这两个可乘函数具有较好的渐近分布性质。
Two new multiplicative functions U(n) and V(n) are defined.By using the analytic methods,mean value about ∑n∈An≤xU(n) and ∑n∈An≤xV(n) are studied,where A denotes the set of all k+1-power free numbers.Two sharp asymptotic formulae are obtained,which shows that these two new multiplicative functions enjoy good distributive properties.
