Lines on K3 quartic surfaces in characteristic 2
arXiv:1606.02135 · doi:10.1093/qmath/haw055
Abstract
We prove that a K3 quartic surface defined over a field of characteristic 2 can contain at most 68 lines. If it contains 68 lines, then it is projectively equivalent to a member of a 1-dimensional family found by Rams and Schütt.
