摘要 Erdős 和 Turán 的经典结果表明,如果一元多项式在单位圆上尺寸较小且其常数系数不太小,则其零点聚集在单位圆附近并在角度上均匀分布。使用傅里叶分析,我们给出了这个结果的简短且独立的证明。
Abstract A classical result of Erdős and Turán states that if a monic polynomial has small size on the unit circle and its constant coefficient is not too small, then its zeros cluster near the unit circle and become equidistributed in angle. Using Fourier analysis we give a short and self-contained proof of this result.
