Equisingular lifting of semi-log canonical $F$ -split $K$ -trivial surfaces

Fabio Bernasconi, Quentin Posva

We show that a projective globally $F$ -split semi-log canonical $K$ -trivial surface over an algebraically closed field of characteristic $p > 0$ admits an equisingular lifting over t…

Pathological MMP singularities as $α_{p}$ -quotients

Quentin Posva

We construct pathological examples of MMP singularities in every positive characteristic using quotients by $α_{p}$ -actions. In particular, we obtain non- $S_{3}$ terminal singularities…
