On linear $α_{p}$ -quotients

Quentin Posva, Linus Rösler, Takehiko Yasuda

We study linear $α_{p}$ -actions on affine spaces and the associated quotient singularities, using explicit stacky resolutions. We describe when the quotient singularities are log can…

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…
