The Blanchet-Khovanov algebras
Michael Ehrig, Catharina Stroppel, Daniel Tubbenhauer
Blanchet introduced certain singular cobordisms to fix the functoriality of Khovanov homology. In this paper we introduce graded algebras consisting of such singular cobordisms à l…

Koszul gradings on Brauer algebras
Michael Ehrig, Catharina Stroppel
We show that the Brauer algebra over the complex numbers for an integral parameter delta can be equipped with a grading, in the case of delta being non-zero turning it into a grade…
