Research Abstract |
(1) We obtained a classification of automorphism groups of smooth plane curves. (2) We classified automorphism groups of curves on Hirzebruch surfaces (joint work with Akira Ohbuchi). (3) We studied Weierstrass semigroups of double coverings of smooth plane quartics (joint work with Jiryo Komeda). (4) We studied the minimal degree of plane models of algebraic curves and obtained a classification of some special curves (joint work with Akira Ohbuchi). (5) We studied linear systems on algebraic surfaces containing curves with different invariants (joint work with Takao Kato and Akira Ohbuchi). (6) We studied the minimal degree of embeddings of curves into projec tive spaces. (7) We determined the number of pencils of minimal degree on curves of small genus (joint work with Akira Ohbuchi).
