    Steffen Oppermann (NTNU Trondheim), Higher dimensional Auslander-Reiten components.

  • Abstract:
    This talk is based on ongoing joint work with Martin Herschend.
    In higher dimensional Auslander-Reiten theory the notion of almost split sequences depends on the choice of a suitable subcategory of a module category. We suggest an axiomatic definition such subcategories, and explore examples and properties.
