Affine Surfaces with Trivial Makar-limanov Invariant
We study the class of 2-dimensional affine k-domainsR satisfying ML(R) = k, where k is an arbitrary field of characteristic zero. In particular, we obtain the following result: Let R be a localization of a polynomial ring in finitely many variables over a field of characteristic zero. If ML(R) = K for some field K ⊂ R such that trdeg K R = 2, then R is K-isomorphic to K[X, Y, Z]/(XY − P (Z)) fo...
متن کاملInfinitely Generated Derksen and Makar-limanov Invariant *
In this paper, we give an example of a finitely generated 3-dimensional C-algebra which has infinitely generated Derksen invariant as well as MakarLimaonv invariant.
متن کاملMakar - Limanov ’ s conjecture on free subalgebras ∗
It is proved that over every countable field K there is a nil algebra R such that the algebra obtained from R by extending the field K contains noncommutative free subalgebras of arbitrarily high rank. It is also shown that over every countable field K there is an algebra R without noncommutative free subalgebras of rank two such that the algebra obtained from R by extending the field K contain...
متن کاملOn the Makar-limanov, Derksen Invariants, and Finite Automorphism Groups of Algebraic Varieties
A simple method of constructing a big stock of algebraic varieties with trivial Makar-Limanov invariant is described, the Derksen invariant of some varieties is computed, the generalizations of the Makar-Limanov and Derksen invariants are introduced and discussed, and some results on the Jordan property of automorphism groups of algebraic varieties are obtained.
متن کاملAffine T-varieties of complexity one and locally nilpotent derivations
Let X = SpecA be a normal affine variety over an algebraically closed field k of characteristic 0 endowed with an effective action of a torus of dimension n. Let also ∂ be a homogeneous locally nilpotent derivation on the normal affine Zn-graded domain A, so that ∂ generates a k+-action on X. We provide a complete classification of pairs (X,∂) in two cases: for toric varieties (n = dimX) and in...
