WebThere are broader forms of Hilbert’s fourteenth problem, for example about actions of algebraic groups on arbitrary affine varieties. Since even the most specific form of the … WebThen the fourteenth problem of Hilbert asks whether or not K fl R is a finitely generated algebra over k. Nagata [3] gave the first counterexample to this problem which is the invariant subring of the additive group scheme G, acting algebraically on a polynomial ring. Recently, Roberts [4] gave a new counterexample to the same problem which is ...

WebFeb 13, 2002 · Smale's problems are a list of 18 challenging problems for the twenty-first century proposed by Field medalist Steven Smale. These problems were inspired in part by Hilbert's famous list of problems presented in 1900 (Hilbert's problems), and in part in response to a suggestion by V. I. Arnold on behalf of the International Mathematical Union … WebHilbert’s 14th problem that we discuss is the following question: If an algebraic group G acts linearly on a polynomial algebra S, is the algebra of invariants SG finitely generated?
