Rational real algebraic models of compact differential surfaces with circle actions
Adrien Dubouloz, Charlie Petitjean
We give an algebro-geometric classification of smooth real affine algebraic surfaces endowed with an effective action of the real algebraic circle group up to equiva…

Smooth contractible threefolds with hyperbolic -actions via ps-divisors
Charlie Petitjean
The aim of this note is to give an alternative proof of a theorem of Koras and Russell, that is, a characterization of smooth contractible affine varieties endowed with a hyperboli…

Smooth varieties with torus actions
Alvaro Liendo, Charlie Petitjean
In this paper we provide a characterization of smooth algebraic varieties endowed with a faithful algebraic torus action in terms of a combinatorial description given by Altmann an…
