摘要
奇完全数的存在性问题是一个著名的数论难题.研究了不被3整除的奇完全数相异素因子个数,证明:如果n是奇完全数,则ω(n)≥16,其中ω(n)表示为奇完全数n相异素因子的个数.
The existence of odd perfect numbers is a well-known open problem in number theory.We prove that if n is an odd perfect number which is relatively prime to 3,then ω(n)≥16,whereω(n) is the number of distinct prime factors of n.
