在短区间内至少有两个因子的整数的分布

The distribution of integers with at least two divisors in a short interval

Kevin Ford, Gerald Tenenbaum

摘要:

令H(x,y,z)是在(y,z]中具有除数的整数$\le x$的个数,令H_1(x,y,z)是具有恰好一个这样的除数的整数$\le x$的个数。当y和z接近时,期望H_1(x,y,z)H(x,y,z),即在(y,z]中具有除数的整数通常只有一个。我们确定了关于y和z的充要条件,使得H_1(x,y,z)H(x,y,z).在这样做的时候,我们回答了一个开放的问题,从文件“的分布整数与除数在一个给定的区间”,数学。NT/0401223。

英文摘要:

Let H(x,y,z) be the number of integers $\le x$ with a divisor in (y,z] and let H_1(x,y,z) be the number of integers $\le x$ with exactly one such divisor. When y and z are close, it is expected that H_1(x,y,z) H(x,y,z), that is, an integer with a divisor in (y,z] usually has just one. We determine necessary and sufficient conditions on y and z so that H_1(x,y,z) H(x,y,z). In doing so, we answer an open question from the paper "The distribution of integers with a divisor in a given interval", math.NT/0401223.
