| Outline of Final Research Achievements |
A research collaboration person and I wrote the article on the conditions for Weierstrass semigroups gained from those of ramification points of double coverings, which was published. An overseas collaborator and I wrote the articles on the Weierstrass semigroups of the ramification points of double covering of plane curves of degree 6 (resp. 5) over total flexes (resp. total flexes and non-ordinary flexes), which were also published. The articles on Galois Weierstrass points (resp. Riemann constants) were published. Those papers are joint works with research collaboration people. Moreover, the other two accepted articles were published.
The three papers were published in the research reports of my university and the other three articles were published in RIMS Kokyuroku. Moreover, the number of oral presentations in workshops is 11. A research collaboration person and I organized the symposium on algebraic curves every year.
