Title: Pairwise Completability for 2-Simple Minded Collections.

Abstract:  Let Lambda be a basic, finite dimensional algebra over an arbitrary field, and let mod(Lambda) be the category of finitely generated right modules over Lambda. A 2-term simple minded collection is a special set of modules that generate the bounded derived category for mod(Lambda). In this talk we describe how 2-term simple minded collections are related to finite semidistributive lattices, and we show how to model 2-term simple minded collections for the preprojective algebra of type A.
