Research Abstract |
Dr. Eklof's research has generally dealt with applications of mathematical logic, specifically model theory and set theory, to algebra, specifically abelian group theory, module theory, and homological algebra. This has included the model theory of modules as well as properties of abelian groups expressible in various extensions of first order logic. In recent years, the main focus has been on algebraic results which are provably unsolvable in ordinary set theory or are solved using methods from combinatorial set theory. A major monograph on this subject, co-authored orignially with the late Alan Mekler, was published in 1990; a revised and expanded edition was published in 2002. His work, with Jan Trlifaj, has provided the key element of a recent proof of a long standing conjecture, the Flat Cover Conjecture and applied set-theoretic methods to module theory and representation theory. | |
