The study of Gorenstein algebras has emerged as a cornerstone of modern algebra, offering a powerful paradigm in which duality and symmetry in module theory can be rigorously examined. These algebras ...

The object of this paper is to study the relationship between certain projective modules and their endomorphism rings. Specifically, the basic problem is to describe the projective modules whose ...

A new and more elementary proof is given for Lønsted's theorem that vector bundles over a finite complex can be represented by projective modules over a noetherian ring. The rings obtained are ...
