We prove some new results about the spacing between neighboring zeros of paraorthogonal polynomials on the unit circle. Our methods also provide new proofs of some existing results. The main tool we will use is a formula for the phase of the appropriate Blaschke product at points on the unit circle.

单位圆上正交多项式的零间距

我们证明了关于单位圆上正交多项式的相邻零之间的间距的一些新结果。我们的方法还提供了一些现有结果的新证明。我们将使用的主要工具是单位圆上各点处相应Blaschke乘积的相位公式。
