    Sondre Kvamme (Paris Sud), Morphisms determined by objects in higher Auslander-Reiten theory.

  • Abstract:
    The concept of a morphism determined by an object was introduced by Auslander as a generalization of the notion of right and left almost split morphisms. For Artin algebras he gave an explicit description of an object which determines a given morphism. We will give a generalization of this result to d-cluster tilting subcategories of Artin algebras. This is based on a joint work with Gustavo Jasso.
