In this paper all coordinates in two variables over a Noetherian Q-domain of Krull dimension one are proved to be stably tame. In order to do this, some results concerning stable tameness of polynomials in general are shown. Furthermore, we deduce that all automorphisms in two variables over a Noeth

β¦ Synopsis
A contemporary approach to studying commutative rings is to take a given theorem for abelian groups, then interpret the statement for a ring R. The validity of the new statement for R usually imposes some w x restrictions upon the structure of R. Warfield 32 showed that for torsion-free abelian groups A and B, when A has rank 1, the natural map Ε½ . Hom A, B m A Βͺ B is an embedding with image equal to the En dΕ½ A.

A commutative ring R has the unique decompositions into ideals (UDI) property if, for any module L that decomposes into a ΓΏnite direct sum of ideals, the decomposition of L into ideals is unique apart from the order of the ideals. We characterize the UDI Noetherian integral domains.
