Fusion modules and amenability of coideals of compact and discrete quantum groups

Benjamin Anderson-Sackaney, Leonid Vainerman

We give a definition of an amenable fusion module over a fusion algebra. A notion of relative integrability for the `coduals' of coideals of compact quantum groups was recently int…

Yetter-Drinfel'd algebras and coideals of Weak Hopf -Algebras

Leonid Vainerman, Jean-Michel Vallin

We characterize braided commutative Yetter-Drinfeld -algebras over weak Hopf -algebras in categorical terms. Using this, we then study quotient type coideal subalgebras o…

Classifying (Weak) Coideal Subalgebras of Weak Hopf C*-Algebras

Leonid Vainerman, Jean-Michel Vallin

We develop a general approach to the problem of classification of weak coideal C*-subalgebras of weak Hopf C*-algebras. As an example, we consider weak Hopf C*-algebras and their w…

On Z/2Z-extensions of pointed fusion categories

Leonid Vainerman, Jean-Michel Vallin

We give a classification of Z/2Z-graded fusion categories whose 0-component is a pointed fusion category. A number of concrete examples is considered.

The Tambara-Yamagami categories and 3-manifold invariants

Vladimir Turaev, Leonid Vainerman

We prove that if two Tambara-Yamagami categories TY(A,χ,ν) and TY(A',χ',ν') give rise to the same state sum invariants of 3-manifolds and the order of one of the groups A, A' is od…

The bicrossed product construction for locally compact quantum groups

Leonid Vainerman

The cocycle bicrossed product construction allows certain freedom in producing examples of locally compact quantum groups. We give an overview of some recent examples of this kind…
