Get Almost Free Modules: Set-theoretic Methods (North-Holland PDF

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

This e-book offers a accomplished exposition of using set-theoretic tools in abelian workforce conception, module concept, and homological algebra, together with functions to Whitehead's challenge, the constitution of Ext and the life of almost-free modules over non-perfect jewelry. This moment version 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 evidence of the Flat disguise Conjecture, in addition to using Shelah's pcf thought to constuct virtually loose teams. As with the 1st version, the ebook is basically self-contained, and designed to be obtainable to either graduate scholars and researchers in either algebra and good judgment. they'll locate there an advent to robust recommendations which they might locate invaluable of their personal work.
