40 - M. Behboodi (Joint with S. H. Shojaee), Commutative local rings whose ideals are direct sum of cyclic modules, Algebr. Represent Theor. (2013), DOI: 10.1007/s10468-013-9427-x

A well-known result of Köthe and Cohen-Kaplansky states that a commutative ring R has the property that every R-module is a direct sum of cyclic modules if and only if R is an Artinian principal ideal ring. This motivated us to study commutative rings for which every ideal is a direct sum of cyclic modules. Recently, in Behboodi et al. Commutative Noetherian local rings whose ideals are direct sums of cyclic modules (J. Algebra 345:257–265, 2011) the authors considered this question in the context of finite direct products of commutative Noetherian local rings. In this
paper, we continue their study by dropping the Noetherian condition.
