Measuring Modules: Alternative Perspectives in Module Theory
Dr. Sergio Lopez-Permouth / Ohio University
We will consider various new ways to gauge the projectivity or injectivity of modules. As an illustration of the usefulness of these new approaches and in contrast with the traditional approach when research has focused on modules which are "as projective (or injective) as possible", we will focus on modules which are weakest in terms of projectivity or injectivity. We will show how all of these related notions are interesting in their own right.
