    • The Grothendieck Group of an n-exangulated Category 

      Haugland, Johanne (Peer reviewed; Journal article, 2021)
      We define the Grothendieck group of an n-exangulated category. For n odd, we show that this group shares many properties with the Grothendieck group of an exact or a triangulated category. In particular, we classify dense ...

    • Totally Acyclic Approximations 

      Bergh, Petter Andreas; Jorgensen, David A.; Moore, W. Frank (Journal article; Peer reviewed, 2021)
      Let Q→R be a surjective homomorphism of Noetherian rings such that Q is Gorenstein and R as a Q-bimodule admits a finite resolution by modules which are projective on both sides. We define an adjoint pair of functors between ...
