Abstract

We show a general method for studying the category of flat modules in terms of indecomposable cotorsion modules (i.e., flat modules C such that $Ext1(F,C)=0 or any other flat module F). We also show how this technique can be extended for studying finitely accessible additive categories, cotorsion theories or certain Model Structures in categories of sheaves.
