函数域中两个平方和与其它算术函数的相关性

Correlations of sums of two squares and other arithmetic functions in function fields

Lior Bary-Soroker, Arno Fehm

摘要:

我们调查一个函数场模拟最近猜想的两个平方和的自相关由弗赖贝格,Kurlberg和Rosenzweig,这概括了一个老猜想康纳斯和基廷。特别是,我们提供了广泛的数值证据,并证明它在大有限域限制。我们的方法也可以处理其他算术函数的相关性,我们给出的应用程序(功能领域的类似物)的两个平方和移位素数的平均值,并自相关性较高的除数函数扭曲的二次字符。

英文摘要:

We investigate a function field analogue of a recent conjecture on autocorrelations of sums of two squares by Freiberg, Kurlberg and Rosenzweig, which generalizes an older conjecture by Connors and Keating. In particular, we provide extensive numerical evidence and prove it in the large finite field limit. Our method can also handle correlations of other arithmetic functions and we give applications to (function field analogues of) the average of sums of two squares on shifted primes, and to autocorrelations of higher divisor functions twisted by a quadratic character.
