摘要:

数论中的一个古老开放问题是 Chebotarev 密度定理在短区间内是否成立。更确切地说,给定 $\mathbb{Q}$ 的一个伽罗瓦扩张 $E$,其伽罗瓦群为 $G$,$G$ 中的一个共轭类 $C$ 以及 $1\geq \varepsilon>0$,人们希望计算 Frobenius 共轭类在 $E$ 中等于 $C$ 且满足 $x\leq p\leq x+x^{\varepsilon}$ 的素数 $p$ 的个数的渐近行为。随着 $\varepsilon$ 变小,难度也随之增加。假设广义黎曼猜想成立,人们仅能达到 $1\geq\varepsilon>1/2$ 的范围。我们针对任意 $\varepsilon>0$ 建立了短区间内 Chebotarev 定理的函数域类比。我们的结果在有限域的规模趋于 $\infty$ 且扩张在无穷远处为弱分歧时成立。这些方法基于高维显式 Chebotarev 定理,并应用于更一般的算术函数背景中,我们将其命名为 $G$-分解算术函数。

英文摘要:

An old open problem in number theory is whether Chebotarev density theorem holds in short intervals. More precisely, given a Galois extension $E$ of $\mathbb{Q}$ with Galois group $G$, a conjugacy class $C$ in $G$ and an $1\geq \varepsilon>0$, one wants to compute the asymptotic of the number of primes $x\leq p\leq x+x^{\varepsilon}$ with Frobenius conjugacy class in $E$ equal to $C$. The level of difficulty grows as $\varepsilon$ becomes smaller. Assuming the Generalized Riemann Hypothesis, one can merely reach the regime $1\geq\varepsilon>1/2$. We establish a function field analogue of Chebotarev theorem in short intervals for any $\varepsilon>0$. Our result is valid in the limit when the size of the finite field tends to $\infty$ and when the extension is tamely ramified at infinity. The methods are based on a higher dimensional explicit Chebotarev theorem, and applied in a much more general setting of arithmetic functions, which we name $G$-factorization arithmetic functions.
