Algebraic curves admitting the same Galois closure for two projections
A criterion for the existence of a plane model of an algebraic curve such
that the Galois closures of projections from two points are the same is
presented. As an application, it is proved that the Hermitian curve in positive
characteristic coincides with the Galois closures of projections of some plane
curve from some two non-uniform points.Comment: 6 page
