正对角二元二次型并的稠密性

Density of the union of positive diagonal binary quadratic forms

Yijie Diao

摘要:

设$X$是一个足够大的正整数。我们证明了,可以选择一个子集$S$的素数与基数$O(\log X)$,使得一个正比例的整数小于$X$可以表示为$x^2 + p y^2$至少有一个$p \in S$。

英文摘要:

Let $X$ be a sufficiently large positive integer. We prove that one may choose a subset $S$ of primes with cardinality $O(\log X)$, such that a positive proportion of integers less than $X$ can be represented by $x^2 + p y^2$ for at least one of $p \in S$.
