关于Erds和Ivi的一个问题

ON A PROBLEM OF ERDOS AND IVIC

令ω(n)表示正整数n的不同素因子的个数,Ω(n)表示正整数n的全部素因子的个数.

Let as usual ω(n) and Ω(n) denote the number of distinct prime factors and the number of total prime factors of n, respectively. Our result are contained in the following theorems.Thus settle a conjecture of Erdos and Ivie.
