摘要：

For a smooth plane curve C subset of P-2, we call a point P is an element of P-2 a Galois point if the point projection pi(P) : C -> 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.
