A remark on a Nagell-Lutz type statement for the Jacobian of a curve of genus 2 and a (2, 3, 6) quasi-torus decomposition of a sextic with 9 cusps
Hiro-o Tokunaga, Yukihiro Uchida
In this note, an analogous statement to the Nagell-Lutz theorem does not hold for the Jacobian of a certain curve of genus 2 over . As a by-product, we give a (2, 3,…

A note on the topology of arrangements for a smooth plane quartic and its bitangent lines
Shinzo Bannai, Hiro-o Tokunaga, Momoko Yamamoto
In this paper, we give a Zariski triple of the arrangements for a smooth quartic and its four bitangents. A key criterion to distinguish the topology of such curves is given by a m…

On the Abel-Jacobi map of an elliptic surface and the topology of cubic-line arrangements
Shinzo Bannai, Hiro-o Tokunaga
Let be an elliptic surface over a smooth curve with a section . We denote its generic fiber by . For a divisor on , we canonically associate a -rationa…
