The category of extensions and a characterisation of n-exangulated functors
Bennett-Tennenhaus, Raphael; Haugland, Johanne; Sandøy, Mads Hustad; Shah, Amit (Peer reviewed; Journal article, 2023)Additive categories play a fundamental role in mathematics and related disciplines. Given an additive category equipped with a biadditive functor, one can construct its category of extensions, which encodes important ... -
Higher homological algebra and support varieties
Sandøy, Mads Hustad (Doctoral theses at NTNU;2021:270, Doctoral thesis, 2021) -
On support varieties and tensor products for finite dimensional algebras
Bergh, Petter Andreas; Sandøy, Mads Hustad; Solberg, Øyvind (Peer reviewed; Journal article, 2020)It has been asked whether there is a version of the tensor product property for support varieties over finite dimensional algebras defined in terms of Hochschild cohomology. We show that in general no such version can ... -
Support Varieties for Finite Dimensional Algebras
Sandøy, Mads Hustad (Master thesis, 2016)We give a presentation of the theory of support varieties for finite dimensional algebras A using the Hochschild cohomology ring. Our presentation is especially focused on the finite generation hypotheses an algebra must ...
