On the characterization of Danielewski surfaces by their automorphism group
Alvaro Liendo, Andriy Regeta, Christian Urech
In this note we show that if the automorphism group of a normal affine surface is isomorphic to the automorphism group of a Danielewski surface, then is isomorphic to a Dan…

On toric ind-varieties and pro-affine semigroups
Roberto Díaz, Alvaro Liendo
An ind-variety is an inductive limit of closed embeddings of algebraic varieties and an ind-group is a group object in the category of ind-varieties. These notions were first intro…

Lie algebras of vertical derivations on semiaffine varieties with torus actions
Ivan Arzhantsev, Alvaro Liendo, Taras Stasyuk
Let X be a normal variety endowed with an algebraic torus action. An additive group action on X is called vertical if a general orbit of is contained in the closure of an o…
