WebAbstract We generalize Roberts' counterexample to the fourteenth problem of Hilbert, and give a sufficient condition for certain invariant rings not to be finitely generated. It shows that there exist a lot of counterexamples of this type. We also determine the initial algebra of Roberts' counterexample for some monomial order Citation WebThe problem of finite generation of the kernel of a derivation is an important special case of the Fourteenth Problem of Hilbert. Let D be a derivation of K(X) over K, i.e., a K-linear map K(X) !

WebThe kernel of a certain derivation of the polynomial ring k [6] is shown to be nonfinitely generated over k (a field of charactersitic zero), thus giving a new counterexample to Hilbert's Fourteenth Problem. As a corollary, we obtain a new proof for Roberts' well-known counterexample in dimension seven. Download to read the full article text
