Infinitesimal commutative unipotent group schemes with one-dimensional Lie algebra

Bianca Gouthier

We prove that over an algebraically closed field of characteristic $p > 0$ there are exactly, up to isomorphism, $n$ infinitesimal commutative unipotent $k$ -group schemes of order $p…

Infinitesimal rational actions

Bianca Gouthier

For any finite $k$ -group scheme $G$ acting rationally on a $k$ -variety, if the action is generically free then the dimension of $Lie (G)$ is upper bounded by the dimension…

Weierstrass semigroups and the order bound

Alix Barraud, YaÄmur ÃakÄ±roÄlu, Bianca Gouthier +2

The aim of this survey is to provide the reader with an essential and accessible introduction to the theory of Weierstrass semigroups, in the context of the theory developed by K.-…
