It is shown that a commutative B´ ezout ring R with compact min- imal prime spectrum is an elementary divisor ring if and only if so is R/L for each minimal prime ideal L1. This

The goal of this work is to exhibit a class of Armendariz rings and a class of non-Armendariz rings. For this purpose, we study the transfer of the Armendariz property to trivial

However at the present time it is unknown if the common multiple condition is either sufficient or necessary for a Jordan ring with unit to have a ring

All groups considered in this paper are abelian and additively writ- ten ; rings are associative and with an identity, modules are unitary... The
