Almost Free Modules: Set-theoretic Methods (North-Holland by P. C. Eklof,A. H. Mekler

By P. C. Eklof,A. H. Mekler

This booklet offers a finished exposition of using set-theoretic equipment in abelian workforce idea, module conception, and homological algebra, together with purposes to Whitehead's challenge, the constitution of Ext and the life of almost-free modules over non-perfect earrings. This moment variation is totally revised and udated to incorporate significant advancements within the decade because the first variation. between those are purposes to cotorsion theories and covers, together with an explanation of the Flat disguise Conjecture, in addition to using Shelah's pcf concept to constuct virtually loose teams. As with the 1st variation, the e-book is basically self-contained, and designed to be available to either graduate scholars and researchers in either algebra and common sense. they're going to locate there an advent to strong concepts which they could locate necessary of their personal work.
