On the number of Galois points for a plane curve in positive characteristic. II. (English) Zbl 1186.14032
Summary: For a smooth plane curve $$C\subset\mathbb P^2$$, we call a point $$P \in \mathbb P^2$$ a Galois point if the point projection $$\pi_P: C \to\mathbb P^1$$ at $$P$$ is a Galois covering. We study Galois points in positive characteristic. We give a complete classification of the Galois group given by a Galois point and estimate the number of Galois points for $$C$$ in most cases.
