The isotropy group of a derivation on a Danielewski-type algebra

Abdessamad Ahouita, Rene Baltazar, M'hammed El Kahoui +1

Given an algebraically closed field $k$ of characteristic zero, we consider in this paper $k$ -algebras of the form $A_{c, q} = k [x, y, z] / (c (x) z - q (x, y)),$ where $c (x) \in k [x]$ …

Rigid Trinomial Varieties

Polina Evdokimova, Sergey Gaifullin, Anton Shafarevich

An algebraic variety $X$ is called rigid if there is no non-trivial action on $X$ of the additive group of the base field. A trinomial variety is an affine variety that is given by…
