    • Change of rings and singularity categories 

      Oppermann, Steffen; Psaroudakis, Chrysostomos; Stai, Torkil Utvik (Journal article, 2019)
      We investigate the behavior of singularity categories and stable categories of Gorenstein projective modules along a morphism of rings. The natural context to approach the problem is via change of rings, that is, the ...

    • Partial Serre duality and cocompact objects 

      Oppermann, Steffen; Psaroudakis, Chrysostomos; Stai, Torkil Utvik (Journal article, 2023)

    • The Ungraded Derived Category 

      Stai, Torkil Utvik (Master thesis, 2012)
      By means of the ungraded derived category we prove that the orbit category of the bounded derived category of an iterated tilted algebra with respect to translation is triangulated in such a way that the canonical functor ...
