Title: Cluster structures for Grassmannians

Abstract: The category of Cohen Macaulay modules over a quotient of a preprojective algebra is a cluster category associated to the coordinate ring of the Grassmannian Gr(k,n).
We study this category and describe some of its indecomposable modules. We also explain how one can associate frieze patterns to them.
