摘要:
给定一个序列ξ:Z_+→C,我们找到一个简单的谱条件,保证泰勒级数F_ξ(z)=∑_{n≥0}ξ(n)z^n/n!的零点在角域内等分布。该条件涵盖了已知的随机和伪随机序列实例,并提供了新的例子,包括Besicovitch几乎周期序列和乘法随机序列。此外,它还条件性地表明梅比乌斯函数μ在二元Chowla猜想下具有此性质。
英文摘要:
Given a sequence $ξ\colon \mathbb Z_+ \to \mathbb C$, we find a simple spectral condition which guarantees the angular equidistribution of the zeroes of the Taylor series \[ F_ξ(z) = \sum_{n\ge 0} ξ(n) \frac{z^n}{n!}\,. \] This condition yields practically all known instances of random and pseudo-random sequences $ξ$ with this property (due to Nassif, Littlewood, Chen-Littlewood, Levin, Eremenko-Ostrovskii, Kabluchko-Zaporozhets, Borichev-Nishry-Sodin), and provides several new ones. Among them are Besicovitch almost periodic sequences and multiplicative random sequences. It also conditionally yields that the Möbius function $μ$ has this property assuming "the binary Chowla conjecture".
