"Factorization in categories of modules"

We study the regularity of the behaviour of the direct sum decomposition in categories of modules. It is well known that in some easy categories the direct sum decomposition is essentially unique. In the last 15 years some interesting examples were found of categories where the decomposition is not essentially unique but there still is an outstanding regularity.
With this seminar we want to present in an elementary way these examples, introducing step by step all the necessary ingredients from monoid theory and module theory.
