范数形式表示很少的整数,但相对较多的素数

Norm forms represent few integers but relatively many primes

Daniel Glasscock

摘要:

范数形式,其例子包括$x^2 + y^2$、$x^2 + x y - 57 y^2$和$x^3 + 2 y^3 + 4 z^3 - 6 x y z$,是由数域上的范数产生的整数形式。证明了由范数形式表示的整数集合的自然密度为零,而由范数形式表示的素数集合的相对自然密度存在且为正.这些结果需要类域理论的工具,包括Artin-Chebotarev密度定理和Hilbert类域。我们介绍这些工具,因为我们需要他们在过程中的主要论点。这篇文章是暂时的性质,并假定只有第一当然代数数论。

英文摘要:

Norm forms, examples of which include $x^2 + y^2$, $x^2 + x y - 57 y^2$, and $x^3 + 2 y^3 + 4 z^3 - 6 x y z$, are integral forms arising from norms on number fields. We prove that the natural density of the set of integers represented by a norm form is zero, while the relative natural density of the set of prime numbers represented by a norm form exists and is positive. These results require tools from class field theory, including the Artin-Chebotarev density theorem and the Hilbert class field. We introduce these tools as we need them in the course of the main arguments. This article is expository in nature and assumes only a first course in algebraic number theory.
