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 ...
