AI总结:

研究二次多项式平方满值的计数函数,并在abc猜想假设下给出更优的上界估计。

摘要:

一个平方满数是指一个正整数,其所有素因子都至少能被它本身整除两次。形如f(n)的平方满整数的计数函数记为S^{{\mathstrut\hspace{0.05em}\blacksquare}}_f(N)。已知对于一个互质对(a,b)∈N×N∪{0},其线性多项式f(x)=ax+b的计数函数为≈_{a,b} N^{1/2}。固定ε>0,对于一个允许的二次多项式f(x),我们证明了对于某个绝对常数varpi<1/2,S^{{\mathstrut\hspace{0.05em}\blacksquare}}_f(N)≪_{ε,f} N^{varpi+ε}。在abc猜想的假设下,我们期望上界为O_{ε,f}(N^ε)。

英文摘要:

A $\textit{square-full}$ number is a positive integer for which all its prime divisors divide itself at least twice. The counting function of square-full integers of the form $f(n)$ for $n\leqslant N$ is denoted by $S^{{\mathstrut\hspace{0.05em}\blacksquare}}_f(N)$. We have known that for a relatively prime pair $(a,b)\in\mathbb N\times \mathbb N\cup\{0\}$ with a linear polynomial $f(x)=ax+b$, its counting function is $\asymp_{a,b} N^\frac{1}{2}$. Fix $\varepsilon>0$, for an admissible quadratic polynomial $f(x)$, we prove that $$S^{{\mathstrut\hspace{0.05em}\blacksquare}}_f(N)\ll_{\varepsilon, f} N^{\varpi+\varepsilon}$$ for some absolute constant $\varpi<1/2$. Under the assumption on the $abc$ conjecture, we expect the upper bound to be $O_{\varepsilon,f}(N^\varepsilon)$.
