Reduction of Kummer surfaces modulo 2 in the non-supersingular case
We obtain necessary and sufficient conditions for the good reduction of
Kummer surfaces attached to abelian surfaces with non-supersingular reduction
when the residue field is perfect of characteristic 2. In this case, good
reduction with an algebraic space model is equivalent to good reduction with a
scheme model, which we explicitly construct.
