关于虚二次域类数的相关性

On correlations between class numbers of imaginary quadratic fields

V. Vinay Kumaraswamy

摘要:

设$h(-n)$是具有判别式$-n$的虚二次域的类数。我们建立了一个渐近公式的相关性,涉及$h(-n)$和$h(-n-l)$,在基本的判别式,避免了同余类$1\pmod{8}$。我们的结果是统一的移位$l$,证明使用高斯的身份有关$h(-n)$表示的整数作为三个平方和。我们还证明了类似的结果,涉及$r_Q(n)$,整数$n$的积分正定二次型$Q$的表示数的相关性。

英文摘要:

Let $h(-n)$ be the class number of the imaginary quadratic field with discriminant $-n$. We establish an asymtotic formula for correlations involving $h(-n)$ and $h(-n-l)$, over fundamental discriminants that avoid the congruence class $1\pmod{8}$. Our result is uniform in the shift $l$, and the proof uses an identity of Gauss relating $h(-n)$ to representations of integers as sums of three squares. We also prove analogous results on correlations involving $r_Q(n)$, the number of representations of an integer $n$ by an integral positive definite quadratic form $Q$.
