On Kummer type construction of supersingular K3 surfaces in characteristic 2

Ichiro Shimada and De-Qi Zhang

Vol. 232 (2007), No. 2, 379–400
Abstract

We show that every supersingular K3 surface in characteristic 2 with Artin invariant at most 2 is obtained by the Kummer-type construction of Schröer.
