This classification is linked with an i...

Orevkov 来源：[J].St. Petersburg Mathematical Journal(IF 0.46), 2019, Vol.31 (1), pp.81-84AMS 摘要：A rational function on a real algebraic curve $C$ is said to be separating if it takes real values only at real points. Such a function gives rise to a covering $\mathbb{R} C\to \mathbb{R}\mathbb{P}^1$. Let $A_1,\dots ,A_n$ be connected components of $\mathbb{R} C$. In a rece...
