高密度无产品集

Product-free sets with high density

Par Kurlberg, Jeffrey C. Lagarias, Carl Pomerance

摘要:

我们证明了存在渐近密度任意接近于1的整数集合,其中方程ab=c无解,其中a,b,c在集合中。我们还考虑了一些自然的推广,以及一个具体的数值例子的产品免费的整数集的渐近密度大于1/2。

英文摘要:

We show that there are sets of integers with asymptotic density arbitrarily close to 1 in which there is no solution to the equation ab=c, with a,b,c in the set. We also consider some natural generalizations, as well as a specific numerical example of a product-free set of integers with asymptotic density greater than 1/2.
