Acyclic curves and group actions on affine toric surfaces
We show that every irreducible, simply connected curve on a toric affine surface X over C is an orbit closure of a G m -action on X.It follows that up to the action of the automorphism group Aut(X) there are only finitely many non-equivalent embeddings of the affine line A …
