Infinitesimal rational actions
Bianca Gouthier
For any finite -group scheme acting rationally on a -variety, if the action is generically free then the dimension of is upper bounded by the dimension…
On the singularities of quotients by 1-foliations
Quentin Posva
We study the singularities of varieties obtained as infinitesimal quotients by -foliations in positive characteristic. (1) We show that quotients by (log) canonical -foliatio…
Fibrations by plane quartic curves with a canonical moving singularity
Cesar Hilario, Karl-Otto Stöhr
We classify fibrations by integral plane projective rational quartic curves whose generic fibre is regular but admits a non-smooth point that is a canonical divisor. These fibratio…
Generalizations of quasielliptic curves
Cesar Hilario, Stefan Schröer
We generalize the notion of quasielliptic curves, which have infinitesimal symmetries and exist only in characteristic two and three, to a remarkable hierarchy of regular curves ha…
