Research Abstract |
(1) I completely settled the distribution of Galois points for a smooth plane curve in positive characteristic. (2) Generalizing the Klein quartic in characteristic two, I gave a family of curves with at least two Galois points. (3) I showed that Galois points for a certain rational plane curve coincide with rational points over a finite field. (4) As a joint work with Homma and Kim, we showed that the curves in (3) induce good algebraic-geometric codes. (5) As a joint work with Miura, we studied the relationship between Galois points and dual curves (in characteristic zero), and showed that the dual curve of a smooth plane curve does not have a Galois point.
