On Kummer type construction of supersingular K3 surfaces in characteristic 2

Ichiro Shimada, De-Qi Zhang

We show that every supersingular K3 surface in characteristic 2 with Artin invariant less than or equal to 2 is obtained by the Kummer type construction of Schroeer.

Characterization of the 4-canonical birationality of algebraic threefolds

Meng Chen, De-Qi Zhang

In this article we present a 3-dimensional analogue of a well-known theorem of E. Bombieri (in 1973) which characterizes the bi-canonical birationality of surfaces of general type.…
