设K是一个数域,其中n > 2,且包含n次单位根。本文证明了由K的n阶特征标的Hecke L-函数的中心值构成的一类二重Dirichlet级数的一致次凸性。主要的新成分,可能是独立的利益,是一个大筛的n阶字符。作为这个工具的进一步应用,我们得到了关于n阶Hecke特征标的L(s,\chi)的几个结果:临界线上二阶矩的估计,中心点的非零结果,以及零密度定理.
Let K be a number field containing the n-th roots of unity for some n > 2. We prove a uniform subconvexity result for a family of double Dirichlet series built out of central values of Hecke L-functions of n-th order characters of K. The main new ingredient, possibly of independent interest, is a large sieve for n-th order characters. As further applications of this tool, we derive several results concerning L(s,\chi) for n-th order Hecke characters: an estimate of the second moment on the critical line, a non-vanishing result at the central point, and a zero-density theorem.
