-actions on contractible threefolds

Shulim Kaliman, Nikolai Saveliev

Let be a smooth contractible affine algebraic threefold with a nontrivial algebraic -action on it. We show that is rational and the algebraic quotient $X//{\bf C…

Subrings invariant under endomorphisms

Shulim Kaliman

Let S and R be the rings of regular functions on affine algebraic varieties over a field of characteristic 0, R be embedded as a subring in S, and F : S --> S be an endomorphism su…

Free C_+ -actions on C^3 are translations

Shulim Kaliman

Let X' be a smooth contractible three-dimensional affine algebraic variety with a free algebraic C_+ -action on it such that S =X'// C_+ is smooth. We prove that X' is isomorphic t…
