We improve Kemper's algorithm for the computation of a noetherian normalization of the invariant ring of a finite group. The new algorithm, which still works over arbitrary coefficient fields, no longer relies on algorithms for primary decomposition.

Let R be a hereditary Noetherian prime ring. We determine a full set of invariants for the isomorphism class of any finitely generated projective R-module of uniform dimension at least 2. In particular we prove that P โ X โผ = Q โ X implies P โผ = Q whenever P has uniform dimension at least 2. Among t
On dit qu'une partie d'un anneau intรจgre est pleine si les polynรดmes ร valeurs entiรจres sur cette partie le sont aussi sur ranneau tout entier. On montre que, sur un anneau noethรฉrien de dimension 1 , ร corps rรฉsiduels finis et localement analytiquement irrรฉductible, les parties pleines sont les par
A module M is known to be a CS-module or an extending module if every ลฝ . complement submodule of M is a direct summand. It is shown that i a simple ring R must be right noetherian if every cyclic singular right R-module is CS, and ลฝ . ii over a simple ring R if every proper cyclic right module is
