The isomorphism problem for commutative monoid rings’
نویسنده
چکیده
By substantial changes and corrections in Demushkin’s old paper the essentially final positive answer to the isomorphism problem for monoid rings of submonoids of Z’ is obtained. This means that the underlying monoid is shown to be determined (up to isomorphism) by the corresponding monoid ring. Thereafter the positive answer to the analogous question for the ‘dual’ objects descrete Hodge algebras is derived. @ 1998 Elsevier Science B.V. All rights reserved.

The isomorphism problem for monoid rings of rank 2 monoids *
The main result of this paper is that for a commutative ring R and finitely generated submonoids M and N of Z2 the monoid rings R [M] and R[N] are isomorphic as R algebras if and only if M and N are isomorphic. In the course of proof we derive various results concerning the structure of rank 2 monoids and isomorphisms between the corresponding monoid rings. 1991 Math. Subj. Class.: 13B25, 20M25...
متن کاملThe Isomorphism Relation Between Tree-Automatic Structures
An ω-tree-automatic structure is a relational structure whose domain and relations are accepted by Muller or Rabin tree automata. We investigate in this paper the isomorphism problem for ω-tree-automatic structures. We prove first that the isomorphism relation for ω-treeautomatic boolean algebras (respectively, partial orders, rings, commutative rings, non commutative rings, non commutative gro...
متن کاملSingularities and Direct-sum Decompositions
Let (R; m;k) be a local ring (commutative and Noetherian). We will discuss existence and uniqueness of direct-sum decompositions of nitely generated R-modules. One says that R has nite CM type provided there are only nitely many indecomposable maximal Cohen-Macaulay R-modules up to isomorphism. Among complete equicharacteristic hypersurface rings with k algebraically closed of characteristic 6 ...
متن کاملRelating Rewriting Techniques on Monoids and Rings: Congruences on Monoids and Ideals in Monoid Rings
A rst explicit connection between nitely presented commutative monoids and ideals in polynomial rings was used 1958 by Emelichev yielding a solution to the word problem in commutative monoids by deciding the ideal membership problem. The aim of this paper is to show in a similar fashion how congruences on monoids and groups can be characterized by ideals in respective monoid and group rings. Th...
متن کاملA Hierarchy of Tree-Automatic Structures
We consider ω-automatic structures which are relational structures whose domain and relations are accepted by automata reading ordinal words of length ω for some integer n ≥ 1. We show that all these structures are ω-tree-automatic structures presentable by Muller or Rabin tree automata. We prove that the isomorphism relation for ω-automatic (resp. ω-automatic for n > 2) boolean algebras (respe...
