Prüfer Conditions in an Amalgamated Duplication of a Ring Along an Ideal
Communications in Algebra
We investigate the transfer of some homological properties from a ring R to its amalgamated duplication along some ideal I of R R I, and then generate new and original families of rings with these properties. This construction has been studied, in the general case, and from different points of view of pullbacks, by D'Anna and Fontana  . Also, D'Anna and Fontana,  have considered the case of the amalgamated duplication of a ring, not necessarily in a Noetherian setting, along adoi:10.1080/00927872.2014.897575 fatcat:m2h4fylfyjbdzfhy5j4ojzfmnm
