Everybody knows what a normal gabi-algebra is
Johannes Berger, Paolo Saracco, Joost Vercruysse
Let A be a k-algebra over a commutative ring k. By the renowned Tannaka-Krein reconstruction, liftings of the monoidal structure from k-modules to A-modules correspond to bialgebra…
Non-semisimple link and manifold invariants for symplectic fermions
Johannes Berger, Azat M. Gainutdinov, Ingo Runkel
We consider the link and three-manifold invariants from arXiv:1912.02063, which are defined in terms of certain non-semisimple finite ribbon categories together with…
Monadic cointegrals and applications to quasi-Hopf algebras
Johannes Berger, Azat M. Gainutdinov, Ingo Runkel
For a finite tensor category we consider four versions of the central monad, on . Two of them are Hopf monads, and for pi…
Modified traces for quasi-Hopf algebras
Johannes Berger, Azat M. Gainutdinov, Ingo Runkel
Let H be a finite-dimensional unimodular pivotal quasi-Hopf algebra over a field k, and let H-mod be the pivotal tensor category of finite-dimensional H-modules. We give a bijectio…
Perfect tangles
Johannes Berger, Tobias J. Osborne
We introduce perfect tangles for modular tensor categories. These are intended to generalise the perfect tensors first introduced in the context of a toy model for the AdS/CFT corr…
