Mordell-Weil groups and automorphism groups of elliptic K3 surfaces

Ichiro Shimada

We present a method to calculate the action of the Mordell-Weil group of an elliptic K3 surface on the numerical Néron-Severi lattice of the K3 surface. As an application, we compu…

Zariski multiples associated with quartic curves

Ichiro Shimada

We investigate Zariski multiples of plane curves such that each is a union of a smooth quartic curve, some of its bitangents, and some of its 4-tangent coni…
