Slope filtrations of log $p$ -divisible groups

Kentaro Inoue

Oort-Zink proved that a $p$ -divisible group over a normal base in characteristic $p$ with constant Newton polygon is isogenous to a $p$ -divisible group admitting a slope filtration…

Construction of quasi-canonical liftings of K3 surfaces of finite height in odd characteristic

Kentaro Inoue

We construct a quasi-canonical lifting of a $K 3$ surface of finite height over a finite field of characteristic $p \geq 3$ . Such results are previously obtained by Nygaard-Ogus when…
