Acyclic curves and group actions on affine toric surfaces
I. Arzhantsev, M. Zaidenberg
We show that every irreducible, simply connected curve on a toric affine surface X over the field of complex numbers is an orbit closure of a multiplicative group action on X. It f…

Polyhedral divisors and SL_2-actions on affine T-varieties
Ivan Arzhantsev, Alvaro Liendo
In this paper we classify SL_2-actions on normal affine T-varieties that are normalized by the torus T. This is done in terms of a combinatorial description of T-varieties given by…

Torsors over Luna strata
Ivan V. Arzhantsev
Let G be a reductive group and X be a Luna stratum on the quotient space V//G of a rational G-module V. We consider torsors over X with both non-commutative and commutative structu…
