Rational points of elliptic surfaces and the topology of cubic-line, cubic-conic-line arrangements

S.Bannai, H.Tokunaga and M.Yamamoto

In this paper, we continue the study of the relation between rational points of rational elliptic surfaces and the topology of plane curves. As an application, we give first examples of Zariski pairs of cubic-line arrangements that do not involve inflectional tangent lines.
