Abelian envelopes for interpolation categories of wreath products from monoidal adjunctions
Johannes Flake, Thorsten Heidersdorf, David Hull
We establish the existence of abelian envelopes for interpolation categories of wreath product groups , for a fixed finite group with the symmetric groups , for…

Koszulity for semi-infinite highest weight categories
Thorsten Heidersdorf, Jonas Nehme, Catharina Stroppel
We show that any upper finite or essentially finite highest weight category where the standard objects have linear projective resolutions and the costandard objects have linear inj…

Khovanov algebras of type B and tensor powers of the natural -representation
Thorsten Heidersdorf, Jonas Nehme, Catharina Stroppel
We develop the theory of projective endofunctors for modules of Khovanov algebras of type B. In particular we compute the composition factors and the graded layers of the image…
