本文继续研究圆嵌入的几何形状与其傅里叶系数值之间的关系。首先,我们回答一个问题的Kovalev和杨有关的支持的傅立叶变换的星形嵌入。圆嵌入的一个重要特例是圆到自身上的同胚。在傅立叶支集的单侧界下,这种同胚是与Blaschke乘积有关的有理函数。研究了有理圈同胚的结构,证明了它们在一致拓扑中形成连通集。
This paper continues the investigation of the relation between the geometry of a circle embedding and the values of its Fourier coefficients. First, we answer a question of Kovalev and Yang concerning the support of the Fourier transform of a starlike embedding. An important special case of circle embeddings are homeomorphisms of the circle onto itself. Under a one-sided bound on the Fourier support, such homeomorphisms are rational functions related to Blaschke products. We study the structure of rational circle homeomorphisms and show that they form a connected set in the uniform topology.
